Hi guys!
I have a tree farm setup on an Attack of the B-Team Server (1.6.4) which is underground and at first everything worked just fine. But as we started to build on the surface, the tree farm stopped working, because the trees didn't grow anymore.
I investigated this issue a little bit and it seems that some building directly above the farm was causing troubles.
By browsing through your code, I found out that I can get the tree farm to work again, if I put two layers of dirt high up in the sky above the farm.
Should planting dyed trees underground be allowed or not?

Woops, sorry. Thx for reading anyways =)

Trees have been removed in later versions BTW
