@ASIKOO is experienced in these unpack things. I'm sure he has it.
Send some messages to him.

nume_item.c_str()  

ask @martysama0134. I'm sure, he will give you the source codes of the v40 without any hesitation.

remove static keyword for uCurrentMap

item.GetItemType() != item.ITEM_TYPE_METIN  
more exception:
if not item.GetItemType() in (item.ITEM_TYPE_METIN, item.ITEM_TYPE_ARMOR)  

like this?
void CHARACTER::GiveRandomItemByType(BYTE bType) { if (!(bType > ITEM_NONE && bType <= ITEM_BELT)) // my last item type is belt return; if (bType == ITEM_SKILLBOOK) { GiveRandomSkillBook(); return; } const std::vector<TItemTable>& vItemTable = ITEM_MANAGER::instance().GetTable(); if (vItemTable.empty()) return; while (true) { const int iRandIdx = number(0, vItemTable.size() - 1); const TItemTable& table = vItemTable.at(iRandIdx); if (table.bType == bType) { AutoGiveItem(table.dwVnum); break; } } } char.h
void GiveRandomItemByType(BYTE bType); USAGE:
character->GiveRandomItemByType(ITEM_ARMOR); character->GiveRandomItemByType(ITEM_BELT);

Don't bother other people. 
 
First of all, we know that the system is working properly. I've seen many people are using it.
 
You guys are using martysama source. I don't have that src so I can't help you for that kind of things.
Probably problem is with packets.

1.Make item stackable from proto
2.uiinventory.py:
Find in def __DropSrcItemToDestItemInInventory(self, srcItemVID, srcItemSlotPos, dstItemSlotPos):
elif item.IsMetin(srcItemVID): self.AttachMetinToItem(srcItemSlotPos, dstItemSlotPos) Change:
elif item.IsMetin(srcItemVID) and not item.IsMetin(player.GetItemIndex(dstItemSlotPos)): self.AttachMetinToItem(srcItemSlotPos, dstItemSlotPos) 3.char_item.cpp
Find in case ITEM_METIN:
ITEM_MANAGER::instance().RemoveItem(item, "REMOVE (METIN)"); Change:

polymorph isn't changing race??
 
------------------------
here is an example for real change race:
int pc_change_race(lua_State* L) { const LPCHARACTER ch = CQuestManager::instance().GetCurrentCharacterPtr(); if (!lua_isnumber(L, 1) || !ch) return 0; const BYTE race = static_cast<BYTE>(lua_tonumber(L, 1)); if (race < 0 || race >= MAIN_RACE_MAX_NUM) return 0; ch->SetRace(race); ch->SetSkillGroup(0); ch->ClearSkill(); ch->ClearSubSkill(); if (ch->GetDesc()) ch->GetDesc()->SetPhase(PHASE_SELECT); return 0; }

enum EMobRank { MOB_RANK_PAWN, MOB_RANK_S_PAWN, MOB_RANK_KNIGHT, MOB_RANK_S_KNIGHT, MOB_RANK_BOSS, MOB_RANK_KING, MOB_RANK_MAX_NUM }; if (GetMobRank() == MOB_RANK_BOSS)  

You need an argument like: guild.get_name(pc.get_guild())
if pc.hasguild() then notice_multiline(string.format("%s has killed Beran!", guild.get_name(pc.get_guild())), notice_all) end If you want to do with src,
Find in char_battle.cpp:
if (true == IsMonster() && 2493 == GetMobTable().dwVnum) { if (NULL != pkKiller && NULL != pkKiller->GetGuild()) { CDragonLairManager::instance().OnDragonDead( this, pkKiller->GetGuild()->GetID() ); } else { sys_err("DragonLair: Dragon killed by nobody"); } } Change:
if (true == IsMonster() && 2493 == GetMobTable().dwVnum) { if (NULL != pkKiller && NULL != pkKiller->GetGuild()) { CDragonLairManager::instance().OnDragonDead( this, pkKiller->GetGuild()->GetID() ); ///msg char buffer[25+13+25]; snprintf(buffer,sizeof(buffer), "[GUILD]%s has killed %s.", pkKiller->GetGuild()->GetName(), GetName()); SendNotice(buffer); //end msg } else { sys_err("DragonLair: Dragon killed by nobody"); } }  

You need initialize
main.cpp find:
LogManager log_manager; add:
CEventsManager EventsManager; CAutoNotice AutoNoticeManager; find:
MessengerManager::instance().Initialize(); add:
EventsManager.Initialize(); find:
OXEvent_manager.Destroy(); add:
EventsManager.Destroy(); service.h:
#define ENABLE_AUTO_NOTICE #define ENABLE_AUTO_EVENTS
