Hi
I have a problem my server crash after i updatet to your newer version 2.3. Here is the crash report: https://pastebin.com/xLP7f3Ng .
My server is on 1.12 and i use forge version 2428

2.3.1 now available on CurseForge.

Oops, my bad. Rewritten the exchangers overlay but forgot to move that into client proxy instead of common proxy, will release a fix ASAP.
