Internal Exception throws forgero + rer(Roughly Enough Resources) modded surver with forgero+rer installed clients.

minecraft version: 1.19.2
fabric version: 0.14.12
fabric server launcher version: 0.11.1
mods: forgero + rer and rer dependencies (I tested with curseforge client and install with curseforge client).

I made that the server and client have same mod configuration by copy and paste with sftp.
I removed either of two, this error did not throw.

Client displays:

Connection Lost
Internal Exception: java.net.SocketException: Connection reset

I searched logs, but I cannot find about this error.

Interesting issue. I haven't tried RER, but I'll give it a go to see if I can replicate the exception. No idea what's going on here, but thanks for submitting the issue!

Issue was solved by moving to a static initializer for the gem level loot function.
