server crash in 1.17
crash report

I have this issue too, running medieval weapons 1.1.5 on a Fabric 1.17 server. Clientside only it works perfectly.

I fixed it myself by rebuilding it from source. Here is the link for anyone having the same issue. Use this jar ONLY on the server, you need to use the version downloaded from CurseForge on the client. Thank me later ^^

Fixed it some time ago but haven't released a version, will do it today :) 56d3410

Same here, have no clue how to fix it as well, for some reason, it only does this in a server, when I launch it in my client, it works fine.

Any Help?
