Hey, so basically I've been working on a level for a little while now, and today I noticed there appears to be a invisible wall toward the sides of one of the rooms. (I noticed it since it was trapping an NPC I'd placed there) I swear it was never there before either, almost like there's an extra invisible wall piece there.

Does anyone know of this kind of problem? Is there a way around it? If it helps it occurs twice, both along pieces where I have a "DweFacadeBalconyMid01" placed along a "NorRmBigMid02" wall piece.

(I tried to upload a screeny but it won't let me )
