Now fixed.
The Saplings/ trees numbers don't update. I do run out of trees I can chop, but I have no idea how many trees I have. (It always says 0 saplings and 10 trees.)
Also, if I hold down the "plant a tree button", it freezes and I have to take my finger off the button for it to refresh. Although I think this may have to do with the "limit" of trees that I can't see.
