Description of the problem

I currently have an issue with The Betweenlands Mod, specialy with the dimension, it seems like the dimension are like otherworld.
Animals like pig and cow spawn and otherworld trees spawn. Also no one of mob spawn.
You have here the link of the issue on SevTech : Ages GitHub

How to reproduce:

1. Go to the BetweenLand

Expected result:

A normal dimension generation

Actual result:

A Fully bugged dimension generation

Pictures:

Looks to me like some sort of biome conflict. This is likely not caused by Betweenlands itself, but some other mod overwriting biomes. Could maybe also be caused by SpongeForge or some of your plugins since BL usually works fine in SevTech ages.
