I can confirm this was happening for me too. No edit mode or debug. It was consistent until a couple days ago and then stopped happening randomly without me changing anything. It was happening in both uefn sessions and creative 1.0. I’m not sure if it’s happening today, haven’t had a chance to check. At one point, if I tried to fly while down and out, I’d fall thru the floor and into the water beneath everything. The following respawn became locked in that state and the player would fall thru the floor without needing to fly first to initiate the bug. But like I said, yesterday it was fixed for me tho and I changed nothing so it’s a strange glitch that IDK how to reproduce
