I'm not finding any lack of collision by that underground lake, is it like a walking on top of the walls kind of no collision?
I also found another softlock in there from interacting with one of the minecarts, so don't do that.
On the underground lake bit? Yeah. The 'walk on top' kinda lack of collision. Kinda sensitive to those cuz I run into them all the time when mak8ng maps... Ugh.
Also...
Did not spot the m8ne cart soft l9ck! Ooh! Thx!
