Info on two bugs:
If you start a new game after playing dom3, without exiting the application, then provinces can have "Ghost" neighbors. This causes dominion problems and counts towards the "more than 6 neighbors" bug.
If your province has more than 6 neighbors, and you do not have positive dominion in the 7th neighbor (in map file order), your beneficial scales will decrease in your province. If you also do not have positive dominion in the 1st neighbor, then the beneficial scales will evaporate in your province.
