Minecraft crashing when opening skill tree

[DesuPinkgit]

Using the modpack "DarkRPG" on my own server (fabric 1.20.1). At first it was completely fine . However a few hours in opening the skilltree screen will crash anyone who does it on the server. On single player acts as normal, pressing the keybind opens up the overlay and there are no issues. Issue might fix after a restart on server but that has not been done yet.

Thanks for reporting.

I have seen such crash before, and somehow it was fixed after the person who reported it updated the mod, even though nothing related to it was changed. In your case I would say to verify if server and clients have the same version of the mod, but since you said it worked for some time, this is unlikely to be the reason.

The problem is that the crash report you send and the one I got earlier give no information what actually causes issue, but it is definitely a mod conflict. The fact that it happens after some time make is even harder, so unless you or someone else have or find steps to reproduce this crash, I think I won't be able to help.

Does this mean that now each time someone opens skill tree the client crashes? If so, could I join that server to experience and analyze this crash myself? You can message me on Discord, my nick is pufmat.

So restarted the server this morning and everything has seemingly fixed itself? I haven't changed a single thing since last night when we were playing the whole day. I will keep your discord at hand and if it happens again ill keep the server up send you the ip and mod list just incase its an underlying issue or isolated to me .
Edit- And yes whenever anyone opened the skill tree the client crashed. No issue on the server itself it was just on the client. But in singleplayer i could open it up fine . Both server and clients running extremely similar mods (server having a few other ones for stability)
