[philadelphia killing mach]

I understand what that error means (Exceeded Max_Winding) or at least what to look for to solve the error when compiling but i've taken every non mohaa pk3 file (those that didn't come with the game) out of mohaa totally (put on desktop) and rebuilt my map three times to make sure there wasn't any redundancy or overlapping but i'm still getting that error message when i attempt to compile. i've taken a screenshot (found below via link) of my radiant window and the only thing i can figure is that it has something to do with the 4 giant butresses i have (one on each wall meeting in the middle via catwalk). reason is, i started out with only the one (at the bottom of the map in XY Top View) and was able to compile but when i copied the butress to the three remaining walls, that's when that error start coming up. suggestions ? i've got a bad feeling no matter how many times or how i rebuild this map; i'm going to get this error message.
