Finding room boundary problems?

[blumarble]

(I'm cross posting this one) I'm looking for tips on finding room boundary problems. I have a room -- actually a long corridor with multiple ins & outs -- that is giving me a "room not enclosed" error. I have carefully scanned the boundaries visually and can't see any problems, and I have checked all the walls and they are all "room bounding".
So how do I find the problem?

Put an area separation line somewhere, see the side that works, move or add more lines to find what you're looking for.

Yeah, I would remove and replace the room seperation lines is what I would do to start out... If thats not the case I would try inserting a NEW room.

Hope this helps,
