I was going to mine and I crafted some iron pickaxes but, when I was sorting my inventory one of the iron pickaxes got stuck on the pointer and I tried to move it around or, throw it on the floor but nothing was working. I tried logging out and back in but that didn't work either. This bug is a lot like the bell glitch. I ended up just having to die and respawn to see if that worked and it did. If you have a lot of levels I could see this getting annoying so I hope you can fix it because that would be great!
