In one of my worlds, when I change one of the blocks in my hotbar to another block from my inventory, several blocks in my hotbar change, not just the one selected, so that I end up with multiple blocks the same in my hotbar as you see in the attached photo. This started out as just affecting two blocks earlier today, and now affects three blocks. I've tried rebooting the app, and removing the various texture packs I work with, but it's still happening. I've checked other worlds that I have and so far it is only happening in one of my worlds, but I'm afraid it's going to spread. Anyone else have this problem since the last update? Or know how to correct it?
