To fix 115 in Cradle, you could try to to expand your dominion to 130, that's the 7th neighbor in the map file. 91 should help too, it's the 1st neighbor.
You are right about other provinces, they are vulnerable to the bug too. To fix your dominion in 78, expand your dominion to 82, that's the 7th neighbor. 53 should help too, it's the 1st neighbor.
Time to put your Insane Void Cultists to work at some preaching!
