I'm not sure what to do but when I logged in a few days ago, the game started generating the evilcraft degraded biome in the end. I did not use any kind of environmental accumulator in the end. First it was 5000 blocks out from the end portal, but now it affects an entire cardinal direction. Is there a way I can turn it off so normal worldgen can take over or am I stuck with that?

I'm not really an IT person, so please excuse me if this isn't formatted correctly.
