Issues with mobs.

[drogul8921 0]

In DT, sometimes after I kill all the mobs in a room, one mob remains on the ground with negative HP. On the character I’m using to kill the mobs, I can’t see the mob that should spawn from it. If I check with another character that is inside DT, I only see the correctly spawned mob.

At the same time, I sometimes get the following syserr (not always, but often enough to be concerning), and it seems related to mobs not spawning properly:

Mar 28 17:48:51 :: no sectree for spawn at 1030042 229916 mobvnum 394 mapindex 41
Mar 28 17:48:51 :: no sectree for spawn at 1029204 218580 mobvnum 394 mapindex 41
Mar 28 17:48:51 :: no sectree for spawn at 1027027 223121 mobvnum 394 mapindex 41
Mar 28 17:48:51 :: no sectree for spawn at 1025876 219708 mobvnum 394 mapindex 41
Mar 28 17:48:51 :: no sectree for spawn at 1028572 225464 mobvnum 394 mapindex 41

From this behavior, it seems like a client-side issue. Has anyone encountered this before and can help?
Thank you very much!

Hello,

I am experiencing a persistent and inconsistent issue related to mob synchronization (visual desync) on the client, and I was hoping someone could help me identify the cause.

Problem description:

Sometimes, after killing mobs (especially in DT), one mob remains visually “dead” (lying on the ground with negative HP) on one character.

In addition, I have encountered this issue across multiple maps, where mobs become invisible on one character, while they are visible and behave correctly on another.

This does not happen consistently — the same mob can either spawn correctly or bug out.

Additional observations:

On another character in the same area/dungeon, everything appears normal.

When using a second character that is initially far away and then approaches the main character:

On the main character, I only see a mob lying on the ground while still receiving damage, which suggests an invisible mob is attacking.

On the second character, the same mob is visible and spawned correctly.

Relogging or re-entering the area usually fixes the issue.

What I have already checked:

Full synchronization of client/server files (folders, mob_proto, item_proto, etc.)

Source:
I am using the following reference:
https://metin2.dev/topic/27610-40250-reference-serverfile-client-src-15-available-languages/

I have been working on this source for about 1 year and 6 months, and I had not encountered this issue until recently, before opening it in beta.

If anyone has experienced something similar or has any ideas about what could cause this kind of desync (entity spawn/update/visibility), I would really appreciate your help.

I am also open to paid support if needed.

Thank you.
