I'm sure some of you are annoyed with floating trees just as I. I have a few things in mind to help prevent this. One way is to keep warping the player to the tree if they leave within 5 blocks of it until they chop down all the logs. Another way is to chop down the entire tree with one or two of the blocks removed at the cost of durability per block to your axe. So lets say, your axe has 4 uses left and the tree has 7 logs in it you will be prevented from being able to take it down. If you have another idea, please post it.
