It seems that if I have Optifine installed with Tekkit, then Treecapitator has a rather annoying bug. It still works. I'll hit the tree and all of the block will fall, but they won't always disappear. I'm not entirely sure how else to describe it, but I can collect the wood blocks, and rather than all of the wood and leaves disappearing, they stay there. I can break them and they won't drop anything. Does anyone know a fix?
(Sorry if that explanation was hard to understand)
