I had the same problem. I solved it by creating a new, blank map. Next step was to create a 'prefab' of all the buildings etc that I wanted to use without re-building. Then I dropped the prefabs into the new map, make sure they are on the grid. You probably need to snap/align them to the grid also, then look for errors.......BIG pain in the ass. My rework was pretty painless considering I was nearly finished too. Now I've reworked the entire thing to cut my vis. Never ending process!
