I was just going through the game for the umpteenth time and came across this glitch, but I can't do it again, just take a look

That is a z-warp. If you check out my climb IL it is being used there . Hel Dlc out of bounds use it as well. Same goes for new category in category extensions.

I just knew Janis would jump on a Z warp discovery the second it popped up XD
