Mod Version

Biomes O' Plenty 1.16.1-11.0.0.390

I post this to the Rats dev but maybe you can see what is going on better. AlexModGuy/Rats#349

Heyo, just tried to reproduce on 1.16.4 and couldn't reproduce the issue, my world loads fine every time for me. Are you guys using Ratlantis as well?

I can confirm this, I tried both rats and BOP in my own modpack and when I create a world its fine but then I cant reload it.
