today I found an exploit that has something to do with dying in lava in kitpvp, for some reason it gives you he death screen, but when you get killed by a player you instantly respawn, what this glitch does is it makes your invontory empty so you have to get killed by a player to get the kit selection book, or be able to do /kit, btw this isn't a visual glitch, I tried to click on the slots in my invontory and nothing updated.
PS: this isn't that big of a problem XD it just probaly wasn't intentionaly put into the game.
