well, that's not supposed to happen..

the crash happens because the empty phialing folder returns null if it doesn't have any aspect stored in it. I've inserted a condition in the phialing cabinet to prevent one from putting in any empty phialing folders, and to only accept those that actually do have an aspect stored.

note: this crash seems to only happen when you're looking at one with goggles of revealing or anything that shows aspects in containers.
