When dying in a sky island buffet with the flower forest biome, you are put in a weird glitchy state were you can punch yourself, see inside your head, and see your name tag. Another weird thing is when you punch yourself to death, it says "[Username] has been slain by [Username]" and your character disappears but you dont get the "You died" screen.

This might happen in other buffet world types, but I didn't test that yet.
