t'sup Ky Kiske, welcome to the.Org

1135 is pretty early in a campaign (heck: you got 318 years to go). Personally, I don't see rebellions in provinces 'not mine' as a problem, but an opportunity...that said, I remember quite a few rebellions pre-patch too.

Sadly, tho' I understand some of it, I don't speak Mod-ese, so I can't help you out much modifying your game to make rebellions stop or decrease.

Oh, and this: I think sig's are hard-wired for baby-blue. Sorry.
