Well, in my first mod, I have 4 different biomes, which exist in a new dimension. The problem is that I want the first biome to be the most common, the 2ond and the third to be rare and the last one to be the rarest of all. So, I've set them all to be cold biomes and the diomes weights are the following : 1000, 11, 11 and 2. Yet only 3 of them generate and the 4th one isn't so rare as it was meant to be.
I've also made a forum page about it, but it didn't solve the problem.
How can I make this work?
Thanks in advance.
