Hmm. I had the impression that this had something to do with WorldBuilder. I have never checked it, and really never even thought about it. Could it have any effect in my graphics glitches with BAT?
That checkbox tells Civ to ignore the code and XML changes in CustomAssets (but BlueMarble still works) during the game. It also changes the cheat code so you can't get to the developer console to cheat. I don't think it stops WorldBuilder, but I haven't tried.
