Did Dynamic lighting get screwed up some how???

On one of maps for some reason dynamic lighting is showing walls where there are none.  I have checked all of the layers just in case and I cannot find any lines that would block light.  Yet in the screen shot there is clearly something blocking light.  This is the first time I have ever had this issue and I can find no way to fix it.  Does anyone have any suggestions on how to fix it? Any help would be appreciated.

Hi Drew, Could you supply a screenshot of the Lighting layer?

My guess is that somewhere on your map there is a wall that doesn't belong.  It could have a very acute angle (that can cause bugs sometimes) or it could be make of freehand, that can cause bugs too.  Best way to fix it: Duplicate the page On the duplicate page delete the walls one at a time until you find the wall causing the problem.  On the original page, delete that wall and see if it fixes the problem. If it does, redraw that wall using polygon/line, in multiple segments if necessary. 

I think its an issue with the number of walls and doors.  I copied the map and then deleted 2/3's of it and now the doors block light.  The dimming part of the lighting still goes in and out.  The invisible walls are gone also when I did not touch any of the sections of the map where they were showing up.

Hmm, odd. If you'd like I can come take a look and see if I can tell what is going on.  If so, please private message me an invite. 

Thanks for the offer but after several experiments I believe it is absolutely because of the size of the map and the number of lighting objects.  If I delete large portions of the lighting layer and reduce the door count it works better.
