Not exactly sure what happened here but I think it was because of little tiles.

Another server crashed when right clicking using the hammer tool from little tiles:

It's definitely this mod.

Fixed in the newest version. Thanks for reporting this issue!

Was playing today with latest version of LittleTiles (LittleTiles_BETA_v1.6.0-pre115_mc1.20.1) and it seems that server freezes, if player leaves a blueprint (with a shape) in to inventory, and re-joins server. Being on 1.20.1, and also CreativeCore is on latest version. Might not be the same case here, but just telling the finding, in case it can be helpful.

I am quite unfamiliar with the little tiles mod. So I don't think I had a blueprint. I just made the hammer and then tried to edit an oak log. This happened three or four times in different versions of the little tiles mod but maybe I just need to update the creative core to the most recent version.... idk

Creative core version : ends in 33

I'm using CreativeCore v2.11.37_mc1.20.1. Haven't used anything else than Little Chisel and Little Blueprint tools so far though. So yeah, it seems that we have faced different kind of server crashes, or at least, by different actions, that leaded to crashing.

Seems to be an issue with the diet mod. I reported the issue to them: illusivesoulworks/diet#200

Let's hope it can be solved soonish.
