When using the Treeaxe in Twilight some strange behaviour occurs.
On very big trees it simply chucks 1 block and sends the server into a fairly big lag spin (Usually disconnects all players)
On "normal" trees like Canopy, it's takes some of the blocks, but then also sends the server into lag.

Using "All The Forge 11 beta" modpack
