Merge/update not working properly
I tried to update my client from 8.60 to 10.98 but I had several problems ingame, I will post pictures of the bugs. By the way with the regular spr and dat 10.98 client these problems do not occur.

I recorded a video also demonstrating some problems caused by the merge. https://youtu.be/FTgTKliBKBE
If you know of any way I can update my client without bugging like this, please let me know, or maybe there is something I can do to make it work normally.
In the last case I would have to add sprite by sprite in the 10.98 client
yes you better adding sprite by sprite because converting a version to another is not 100% working to just "convert and use", the code is not complete, there are LOTS of item flags/attributes that need to be recreated for the client to read them properly
