what version of c2me, what version of mc, twighlight forest etc?

This is not a c2me issue

c2me-fabric-mc1.17.1-0.2.0+alpha.5.19-all
twilightforest-1.17.1-4.0.860-universal
1.17.1 fabric MC
i think it is a C2ME problem since i dont think another mod would log stuff as C2ME Worker

The c2me worker forwards any message from the vanilia world gen system

Try it without c2me and see if you get the warnings

i dont get the warnings now, but the chunks load again slow AF.
can i manually delete something to repair it?

Try with a backup some time before again without c2me
