Currently the Tree Cutter does not recognize Thaumcraft trees as trees. I'm unsure why as the logs and leaves are properly in the ore-dictionary as logWood and treeLeaves.

First tests ok - as the cutting algorithm focuses on the tree skeleton there are still some issues cutting Greatwood trees completely (there are a whole lot of leaves between the logs). But this is more something that I would call "space for improvement", not an actual bug. So I release this in the current state.

Ok, that is not a compat issue but a quite stupid bug - I forgot to initialize the ore-dict based log lookup, should be fixed in the next beta.

Ok, the beta is on Curse, can you double check and re-open if something does not look right in this matter?
