[WIP] Precipice

Maybe just put a large box over it?
Just a question, what IS phantom BSP?

It's a collision compile error. Usually happens around nearly coplanar surfaces that are vertically oriented (ie walls). Also, it usually only happens around one nearly coplanar error at a time. So, if you fix the problem, the invisible mass just migrates elsewhere.

My advice to Silicon is to try to persevere and fix the problems. The big, featureless abyssal walls look to be the culprit. Add more geometry to break up the big flat surface or just rough it up and make it a rock wall and Tool will be grateful.
