Hey guys, I was looking at the IC2 code to try and see how your rubber trees were being generated, because they aren't appearing the biomes added by my mod TFCraft. I noticed that you are doing a straight check off of the variables in biomegenbase. I think it would be good if you changed your checks from

or
Doing this will allow modded biomes of a similar type to be capable of spawning your rubber trees.
