This issue only happened when a bunch of chunks were being loaded at once and the server was being overloaded. This only stopped when I removed Simple Copper Pipes.

Thanks! Is there any ETA to when this could be happening?

There’s a hurricane coming through soon so idk now LOL
In any case, expect it after you see us releasing Wilder Wild 3.0 and Trailier Tales, as those are both our priority at the moment

Lucky you, being on 1.21.1!
It's likely a FrozenLib issue that I already fixed, but me and Liukrast are working on making it multiloader.
Once that's finished I'll update pipes and you shouldn't have the issue anymore.

Does this happen in the latest release?

Sorry for the late response, I'll check this out soon.
