Major

What happened?

When the "create world" menu is opened, the BYG nether biomes config will invert itself, reversing the lower and upper layers, while leaving the middle layer untouched. This inversion will happen whenever the menu is opened.

The worldgen is based on the state of the config before it was inverted upon opening of the menu, however this means that if the config is still inverted from a previous instance, it will use those inverted configs to generate a new nether, which can cause major issues for those wanting to have certain biomes only spawn on the upper layers or vice versa.

I saw a similar issue that might possibly be related being posted here before, but it was for the fabric loader. The issue in question is #101

Did you isolate BYG?

I tried BYG alone
