Since update I noticed issues mining trees.
I have been making different types of trunks for trees. keeping original wood inside the leaves to keep the tree from decaying, lighting it up under the log, then my replacement trunk to ground.
but now, I cannot mine single blocks of wood from trees.
Now this happens with diamond and iron axes, it mines the whole tree... even when I don't want the whole tree... 
Wood axes, I don't do anything, on any wood, and I get a (First position set to <coords of tree> ) message.
punching trees works as normal. I get the single piece of wood.
