I have the same problem with the Tribulation map when I generate it. The levels connect fine and everything and there are no errors but when I generate the map it makes black squares in the same exact spot to about the center of the map then stops.
Also this is with gmaps that I'm having this problem.
Also at least for me its not a generated level error as the overworld has been completely hand made. Maybe this has something to do with it?
Not directing my comments to you directly Piggy just to any one who might have an idea of whats up.
