Can't generate custom Trees by saplings in custom biomes

[Masy]

As mentioned in the title, it still generates vanilla trees, even though i made a sapling-resource-que. However, the trees are generated by the generator, but just by saplings won't work. And it is a custom Biomes which overrides the Forest biome, if it matters.

same bug

Just reading some random issues and noticed this one. By now i found a fix for this: I used the ReplaceToBiomeName function in those custom biomes. It then uses the Sapling queue of the biome which has been overwritten, so just adding the custom sapling queue to the biome that will be overwritten(?) by the custom biome works. But still, I would consider it as a bug.
