modernfix-fabric-5.0.0+mc1.20 not loading with MoreCulling - v0.18.0 for 1.20.1

Seems like a weird compatibility issue

Seems like it might be due to ModernFix

Yes, deleting ModernFix fixed it, ironic enough.

Hope this is fixed soon, as MoreCulling - v0.19.0 for 1.20.x still has it

Honestly not sure whats causing the conflict

Are you able to re-produce it on your end?
It's still causes freezing on the latest versions of these mods:
moreculling-1.20.1-0.19.0 & modernfix-fabric-5.6.1+mc1.20.1 ;

I cannot confirm on clientside at least, ModernFix 5.7.2 and MoreCulling 0.19.0.

MoreCulling should not be running on servers. Its client-side only
