Hm. You sir are a genius.

I was actually thinking about this and the pathing system should be able to handle this check at less than the cost of pathing a single job nearby. Considering the game also registers rooms, there are checks for if a room is created somewhere which would also make navigation a pinch. Almost seems like it is something I would build in early and by default otherwise I would consider the navigation system critically broken. I don't know how the game is written or structured under the hood but as a programmer and game dev I can take an educated guess and say that if it is structured the way I think it is it would be a 4 hour job tops to just remove this errm "oversight?"
I mean no disrespect to the devs either they have done a great job. I was just chewing on that thought so I thought I'd spit it out here.
