Also flag cases. Side effect might be some odd collision in rare cases w/ portals. Also, might cause unexpected collisions w/ cases in TestColl - although we could add a proximity check to the flag there, or simply switch to TestCollExcludingMe again. uCollisions seems mismatched w/ AI TestColl anyway. Possibly r+1+r vs r+r for gear diametre.
