Issue with Treecapitator and Optifine

[TheStonedAlchemist]

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)

I think its a general optifine bug with the version of forge currently in tekkit(517 i think) and can only be fixed either by waiting until the next update, or by updating forge to V518 or higher
