I've encountered a problem with this mod where colonists will rapidly switch between all the filth in a room; so fast that the colonist will just be stuck in the same tile. If I unassign them from Clean+ (from PriorityClean), they get unstuck and stop trying to clean.

However, if I assign the area they're trying to clean as a cleaning area, they'll clean the area normally. It seems like PriorityClean will try to clean all of the rooms it considers "Sterile" (Kitchen, Laboratory, etc.) even if CleaningArea forbids it, so they fight.
