I did mention bandits.
There are actually multiple types of collision. The collision that would be disabled is the character controller collision checks. If something entered/changed the volume then collision mode would change. We do know how to make this stuff work and if it didn't, I'd have 5 testers telling me in 1.2 seconds.
Ironically, they would possibly be cheaper that the current sleepers, which do have their character controllers on while sitting there.
Not on my radar. I probably have 20 or 40 things to do before that, so likely time will run out.
