I recently decided to mess around with potions on creative. After using the thick potion though, I am no longer able to hit mobs with my hand or other things except for swords, pick axes, axes, shovels, and other tools. This doesn't help me, because I have a mob farm and I don't want to waste my sword on the mobs and just want to punch them...
EDIT: A splash potion of weakness has the same effect, I cannot do anything!
What I expected: I can hit mobs with anything!
What happened: Only tools (swords, shovels, etc.) can damage mobs. ANYTHING ELSE doesn't work.
How to reproduce:
1. Drink a thick potion (splash works too).
2. Attempt to hit a mob with anything but a tool.
Edit: This bug happens on survival and creative.
