This shows up whenever I try to log into my friends server. I tried reinstalling the modpack and playing on a fresh server but issue still occured. I think it may have something to do with apotheosis as is seems to introduce a new shears item and remove the minecraft one.

Is that the root cause of the issue?

issue seems to have fixed itself, no idea what the cause was
