Bug with modded biomes in the overworld.

[SundownGaming]

I added this mod to my server and it now thinks that one of the biomes in the overworlr that were already loaded before, which is also added by another mod, is one of the better end biomes eventhough it's not in the end.
It has caused the grass in the biome to become yellow, thick yellow fog to form whenever I'm in it, and it's changed to betterend:something in the f3 menu (also recognised as that better end biome by another mod that displays names of biomes you walk into at the top of the screen)
The biome itself is still the same with the same trees and terrain it's just that the server doesn't know that for some reason, and this issue occurred with the better Nether mod too. I had added both better end and better nether and then I noticed that the better nether mod somehow transformed one of the modded overworld biomes so I removed it and then the same issue happened in the same biome but this time with a better end biome.
It's not like the biomes have the same name either so I have no clue what's causing this or how to fix it.

This mod is dead. Don't bother opening issues here.
