Not sure if this is known. It didn't seem useful when I first did it but then the collision of a random wall was missing.

btw on another note, Turrell is spelled with two l's and not one.

Huh, interesting! There's also a chance of falling through the floor when you enter Mewsuem, but that seems to be more consistent.

This actually happened to me in Furwakening

The interesting part is that when I passed through the platform, I was able to clip into the building without any trouble. I attempted to replicate it but I just wasn't able to.
