I was in my world doing an experiment on how much TNT it takes to destroy obsidian, when THIS happened. I need this fixed, because as long as the bug is still there, I can't do my experiment! (Unfortunately, I am not able to include my video of it happening. But trust me, it does happen.)
Thank you for your report!
