Newest Gendustry (1.6.3) doesn't work correctly with latest Forestry (4.2.1): mod can't register any bees (= "colored" bees aren't available in game). In the same time Forestry many times reports about fatal error in log: Missing allele: {null, null}.

But with Gendustry 1.6.2 all works fine.

same problem.

It seems problem is caused by GenDustry, not Forestry: I tested 4 times with these versions:

• Forestry 4.2.0 + GenDustry 1.6.2 = works fine
• Forestry 4.2.1 + GenDustry 1.6.2 = works fine
• Forestry 4.2.0 + GenDustry 1.6.3 = Forestry can't register "colored" bees.
• Forestry 4.2.1 + GenDustry 1.6.3 = Forestry can't register "colored" bees.

Custom bee registration should be fixed in this build: http://minecraft.curseforge.com/projects/gendustry/files/2269234

Don't think the log spam is related to this, tho i will look into it.
