Minecraft Username: TM_iBeast Brief Description: You can remove locked heads with water. Instructions: Player 1 places a head down and locks it. Player 2 then pours water over the top and collects the head. Player 2 places it somewhere else. (The head will still say it is locked by Player 1.) Player 2 destroy it with water again and the lock is removed. How many times did you recreate this bug?: At least 5 times. Result: A head that should be locked by someone else. Expected Result: Water shouldn't destroy it. Evidence: No evidence at the moment.
I believe this cannot be fixed, due to the fact that the water-removing-head mechanic is in vanilla minecraft, I belive we cannot fix this issue.
If it's true that it's in vanilla minecraft, then it should directly be reported to Mojang to fix the issue.
The problem is a plugin trying to override vanilla behaviour. It's a vanilla minecraft thing, and it's intended.
Yes. But that event gets called a billion times whenever water spreads. It's laggy and will cause issues.
