Glad you were able to fix your problem. For future reference (or anyone else), the tree leaves thing is not a bug, it's because the LOTR mod "overwrites" the vanilla leaves block with a replacement block that has slightly different behaviour. Forge then interprets this as a block being registered incorrectly with the Ore Dictionary, which is not the case.
