I heard many people receiving handshake from Belize location >_< 
However I don't think your core crash is related to that syserr.
Analyze with #dbg your core crash first of all.
 
About handshake you can decide to blacklist the intrusive ip.
Activate a firewall leaving public only the needed ports, and put some limit or check.

dragon_soul.quest  (or .lua)
It's a LUA drop.  Check in /quest folder.

#include "questmanager.h"  
(It's weird you don't have by default)

Ok for pack, I mean here:

Passing 2 arguments by default. If you extended it, be careful everywhere!

Hello Devs, has been a while since I didn't post anything, so I decided to try to remember some useful thing always in my theme "korean errors".
Let's go:
-1: An other common SQL error in mob_proto is
SELECT * FROM mob_proto WHERE gold_min > gold_max OR damage_min > damage_max; Found anything? Good job!
 
-2: I found in official python (an old version maybe) a silly import in an "OnUpdate Def".
The file was: "uitarget.py" and the import "import event". Check if you have the same problem, I hope no for you.
 
-3: Years ago I posted a fix about the accessory's bonus by slots. The official mt2 in 2018 was showing on tooltip only x2 bonus but was applying x3 (if the item has x3 basic applies) from c++.
Nowadays my fix is wrong if you want to be updated like official, because they fixed the tooltip also for the third bonus. Now I show what I mean.
 
item.cpp
Find:
if (0 != accessoryGrade && i < ITEM_APPLY_MAX_NUM - 1) If you have it like this, it's applying only x2 of 3 basic bonus by slot. So to be correct, change like this:
if (0 != accessoryGrade) Now we can update the python part as official did.
 
uitooltip.py, the function def __AppendAccessoryMetinSlotInfo(...)  should be like this:
def __AppendAccessoryMetinSlotInfo(self, metinSlot, mtrlVnum): ACCESSORY_SOCKET_MAX_SIZE = 3 cur = min(metinSlot[0], ACCESSORY_SOCKET_MAX_SIZE) end = min(metinSlot[1], ACCESSORY_SOCKET_MAX_SIZE) affectType1, affectValue1 = item.GetAffect(0) affectList1 = [0, max(1, affectValue1 * 10 / 100), max(2, affectValue1 * 20 / 100), max(3, affectValue1 * 40 / 100)] affectType2, affectValue2 = item.GetAffect(1) affectList2 = [0, max(1, affectValue2 * 10 / 100), max(2, affectValue2 * 20 / 100), max(3, affectValue2 * 40 / 100)] affectType3, affectValue3 = item.GetAffect(2) affectList3 = [0, max(1, affectValue3 * 10 / 100), max(2, affectValue3 * 20 / 100), max(3, affectValue3 * 40 / 100)] mtrlPos = 0 mtrlList = [mtrlVnum] * cur + [player.METIN_SOCKET_TYPE_SILVER] * (end - cur) for mtrl in mtrlList: affectString1 = self.__GetAffectString(affectType1, affectList1[mtrlPos + 1] - affectList1[mtrlPos]) affectString2 = self.__GetAffectString(affectType2, affectList2[mtrlPos + 1] - affectList2[mtrlPos]) affectString3 = self.__GetAffectString(affectType3, affectList3[mtrlPos + 1] - affectList3[mtrlPos]) leftTime = 0 if cur == mtrlPos + 1: leftTime = metinSlot[2] self.__AppendMetinSlotInfo_AppendMetinSocketData(mtrlPos, mtrl, affectString1, affectString2, affectString3, leftTime) mtrlPos += 1 And now we have to update the function:  __AppendMetinSlotInfo_AppendMetinSocketData(...) like this:
def __AppendMetinSlotInfo_AppendMetinSocketData(self, index, metinSlotData, custumAffectString = "", custumAffectString2 = "", custumAffectString3 = "", leftTime = 0): slotType = self.GetMetinSocketType(metinSlotData) itemIndex = self.GetMetinItemIndex(metinSlotData) if 0 == slotType: return self.AppendSpace(5) slotImage = ui.ImageBox() slotImage.SetParent(self) slotImage.Show() ## Name nameTextLine = ui.TextLine() nameTextLine.SetParent(self) nameTextLine.SetFontName(self.defFontName) nameTextLine.SetPackedFontColor(self.NORMAL_COLOR) nameTextLine.SetOutline() nameTextLine.SetFeather() nameTextLine.Show() self.childrenList.append(nameTextLine) if player.METIN_SOCKET_TYPE_SILVER == slotType: slotImage.LoadImage("d:/ymir work/ui/game/windows/metin_slot_silver.sub") elif player.METIN_SOCKET_TYPE_GOLD == slotType: slotImage.LoadImage("d:/ymir work/ui/game/windows/metin_slot_gold.sub") self.childrenList.append(slotImage) if localeInfo.IsARABIC(): slotImage.SetPosition(self.toolTipWidth - slotImage.GetWidth() - 9, self.toolTipHeight - 1) nameTextLine.SetPosition(self.toolTipWidth - 50, self.toolTipHeight + 2) else: slotImage.SetPosition(9, self.toolTipHeight - 1) nameTextLine.SetPosition(50, self.toolTipHeight + 2) metinImage = ui.ImageBox() metinImage.SetParent(self) metinImage.Show() self.childrenList.append(metinImage) if itemIndex: item.SelectItem(itemIndex) ## Image try: metinImage.LoadImage(item.GetIconImageFileName()) except: dbg.TraceError("ItemToolTip.__AppendMetinSocketData() - Failed to find image file %d:%s" % (itemIndex, item.GetIconImageFileName()) ) nameTextLine.SetText(item.GetItemName()) ## Affect affectTextLine = ui.TextLine() affectTextLine.SetParent(self) affectTextLine.SetFontName(self.defFontName) affectTextLine.SetPackedFontColor(self.POSITIVE_COLOR) affectTextLine.SetOutline() affectTextLine.SetFeather() affectTextLine.Show() if localeInfo.IsARABIC(): metinImage.SetPosition(self.toolTipWidth - metinImage.GetWidth() - 10, self.toolTipHeight) affectTextLine.SetPosition(self.toolTipWidth - 50, self.toolTipHeight + 16 + 2) else: metinImage.SetPosition(10, self.toolTipHeight) affectTextLine.SetPosition(50, self.toolTipHeight + 16 + 2) if custumAffectString: affectTextLine.SetText(custumAffectString) elif itemIndex != constInfo.ERROR_METIN_STONE: affectType, affectValue = item.GetAffect(0) affectString = self.__GetAffectString(affectType, affectValue) if affectString: affectTextLine.SetText(affectString) else: affectTextLine.SetText(localeInfo.TOOLTIP_APPLY_NOAFFECT) self.childrenList.append(affectTextLine) if custumAffectString2: affectTextLine = ui.TextLine() affectTextLine.SetParent(self) affectTextLine.SetFontName(self.defFontName) affectTextLine.SetPackedFontColor(self.POSITIVE_COLOR) if localeInfo.IsARABIC(): affectTextLine.SetPosition(self.toolTipWidth - 50, self.toolTipHeight + 16 + 2 + 16 + 2) else: affectTextLine.SetPosition(50, self.toolTipHeight + 16 + 2 + 16 + 2) affectTextLine.SetOutline() affectTextLine.SetFeather() affectTextLine.Show() affectTextLine.SetText(custumAffectString2) self.childrenList.append(affectTextLine) self.toolTipHeight += 16 + 2 if custumAffectString3: affectTextLine = ui.TextLine() affectTextLine.SetParent(self) affectTextLine.SetFontName(self.defFontName) affectTextLine.SetPackedFontColor(self.POSITIVE_COLOR) if localeInfo.IsARABIC(): affectTextLine.SetPosition(self.toolTipWidth - 50, self.toolTipHeight + 16 + 2 + 16 + 2) else: affectTextLine.SetPosition(50, self.toolTipHeight + 16 + 2 + 16 + 2) affectTextLine.SetOutline() affectTextLine.SetFeather() affectTextLine.Show() affectTextLine.SetText(custumAffectString3) self.childrenList.append(affectTextLine) self.toolTipHeight += 16 + 2 if 0 != leftTime: timeText = (localeInfo.LEFT_TIME + " : " + localeInfo.SecondToDHM(leftTime)) timeTextLine = ui.TextLine() timeTextLine.SetParent(self) timeTextLine.SetFontName(self.defFontName) timeTextLine.SetPackedFontColor(self.POSITIVE_COLOR) if localeInfo.IsARABIC(): timeTextLine.SetPosition(self.toolTipWidth - 50, self.toolTipHeight + 16 + 2 + 16 + 2) else: timeTextLine.SetPosition(50, self.toolTipHeight + 16 + 2 + 16 + 2) timeTextLine.SetOutline() timeTextLine.SetFeather() timeTextLine.Show() timeTextLine.SetText(timeText) self.childrenList.append(timeTextLine) self.toolTipHeight += 16 + 2 else: nameTextLine.SetText(localeInfo.TOOLTIP_SOCKET_EMPTY) self.toolTipHeight += 35 self.ResizeToolTip() -4: I think this is 100% my idea, and it will fix some problem in maps that you don't know.
A simple refactor of the aggregate monster item function. A function very spammed in game and also badly done.
I changed it like this:
 
struct FuncAggregateMonster {     LPCHARACTER m_ch;     FuncAggregateMonster(LPCHARACTER ch) { m_ch = ch; }     void operator()(LPENTITY ent)     {         if (ent->IsType(ENTITY_CHARACTER))         {             const LPCHARACTER ch = (LPCHARACTER) ent;             if (!ch)                 return;             if (ch->IsPC())                 return;             if (!ch->IsMonster())                 return;             if (ch->GetVictim())                 return;             // 85% trigger optimized (do not use 100%)             if (number(0, 100) <= 85)             {                 auto aggRange = 5000; //Default range                 //Example of range reduction, in this case for Ochao Index. You can do it also for mazes or monkey maps.                 //Without this change you can call the boss without making the path, through the walls                 if (ch->GetMapIndex() == 353)                     aggRange = 2600;                 if (DISTANCE_APPROX(ch->GetX() - m_ch->GetX(), ch->GetY() - m_ch->GetY()) <= aggRange)                 {                     if (ch->CanBeginFight())                         ch->BeginFight(m_ch);                 }             }         }     } }; Because is always better to decrease the range in tight places.
 
That's all for now, thanks for reading and hope that been useful.
Check my last release about this themes:
 

Launcher source? 

Korean shits...
 
 
PythonPlayerInput.cpp
DWORD CPythonPlayer::__GetPickableDistance() {     CInstanceBase * pkInstMain = NEW_GetMainActorPtr();     if (pkInstMain)         if (pkInstMain->IsMountingHorse())             return 500;     return 300; } + item.cpp could be enough

Change the name of the folder eg. "ymir work-editor" and retry in game if still get the problem.

Go in your source directories and do the command. It's just a search to understand where is your problem. (you told don't know where is, I think it's not default thing).
 
#  <-  means is a shell command.

http://www.cplusplus.com/reference/cstring/strcmp/

I think It doesn't fix the problem.

This is a "W10 Software Development Kit block". You just have to define in the "windows headers".
Please just check information from microsoft.
 
Here is the fix as I made:

self.TitleName.SetText(localeInfo.EXCHANGE_TITLE % str(exchange.GetNameFromTarget()))  
it looked like a python riddle

Table 'account.string'
Need a table not a column

class ExpandedTaskBar(ui.ScriptWindow):         BUTTON_DRAGON_SOUL = 0     def __init__(self):   BUTTON_DRAGON_SOUL  Must be in line with def. You used 1 tab for def and 2 tabs for variable, python is easy cuz there aren't ; etc.  but if you don't respect TAB rip.   Download notepad++ and use it to see codes.

typedef struct command_player_select
{
    BYTE    header;
    BYTE    index;
} TPacketCGPlayerSelect;
 
You fucked up something, index is 0, name is just 1 character.
-Packet problem
-Database problem

Better a delay with timer in this case.  

Work on this remake, you was fucking the indentation.
