So I started messing about with the Map Editor in FC4, but whenever I zoom about the place I've built, the furniture and doors and all the other objects start flashing in and out of existence, depending on which angle I'm looking at them from. I've tried shutting down the system, but it didn't work. Someone told me that it's caused by objects merging into each other, but I don't think this can be right either, because it kept to objects I placed in the middle of nowhere. It makes the map editor pretty much unplayable to me, so help is very much appreciated!
