I get a crash on a modded server, that is caused when the world loads a fairy circle.

I am using my custom modpack server, modpack: Geosmelt.

Please provide a crash log and/or latest.log

Sorry I thought I included it: https://gist.github.com/TheWitherlord/f33d958f847fbe40dd0940856a29ac49

Hello! Quark's moved to 1.18 now-- unfortunately, this means that (unless your bug is critical and/or game-breaking), we're closing support for issues filed for versions prior to it (e.g. Quark on 1.16).

If your issue still occurs on 1.18, or if your issue happens to be rather critical (e.g. consistently crashing the game with no other mods present), please leave another note or open a new issue. Thanks for your cooperation!
