I've just hit something bizarre in my latest game. AI Taksashila have just their starting province. The capital has the Faction Leader and a garrison in it. They have some minor settlements with troops in and their Faction Heir is out with a small, depleted force. There's some big rebel stacks near them, but not close enough to threaten the capital or Heir in a single turn.

Yet everything turns rebel every single time I move to the next turn. Any idea what's happening? I've increased the garrison in the capital and given them some money via the console, but it doesn't seem to do anything.

Here's a screenshot of their domain:

Also, how do I deactive the generic script?
