Mod name: Collective
Mod version: 3.13

Description

I have a server that wanted to use the Bottle Your Xp mod however Collective causes a crash every time it is loaded and something I have noted is that it gives me the error before the server usually sends the message "Compatibility level set to JAVA_17"

Edit: After Posting this a friend of mine mentioned updating fabric API may help. I tried that It loaded fine without Collective installed, still crashed after I added Collective

I have solved the Issue.

in my case, for some reason it appears to have not and after reinstalling fabric and doublechecking the version it seems to work
