I guess if enough toilets are full, their pathfinding will try to use a trash bin instead. But we don’t really know how severe the change is going to be.
I’m interested in poisoning Ken Morgan in Bangkok after the patch, since the one dinner plate he tastes always makes him go to a trash bin so that you can shoot coconuts on him for a challenge. If that’s changed, then that could be a problem. (Unless it’s scripted that he always goes there)
