What happened?

Description

After updating to the latest otclient-mehah build, the client crashes with repeated errors related to creature movement desync.

The same .dat and .spr files worked fine with my previous otclient build.
This only started happening after updating to the new mehah build.

The client logs spam:

• ProtocolGame::parseCreatureMove: no creature found to move
• ERROR: no thing at pos

Eventually the client crashes.

Environment

• OS: Windows 10/11 x64
• GPU: NVIDIA GeForce RTX 3060
• OpenGL: 4.6 (NVIDIA 572.70)
• OTClient: otclient-mehah (latest opentibiabr build)
• Server: forgottenserver 0.4 (fireelements)
• Protocol: 860
• DAT / SPR: Same files as previous working otclient (confirmed identical)

---

Steps to reproduce

1. Launch otclient-mehah
2. Connect to the server
3. After some creature movements (walking / nearby monsters / players)
4. Client starts logging desync errors and eventually crashes

Well, looking at your terminal, you have a problem with unhandled opcode. The problem is not with the client it self, it is missing custom modifications that you had before. Check the code on your server and understand what it is sending to otcr to be able to
Fix it.

Apparently, the terminal is reporting a position error. It seems there's an item on the map that your spr/dat or items.otb file is missing. Is your map correct? Or it could also be that your spr/dat and items.otb files are misaligned. map.otbm also
