Enemy Rebel Bug?

[unmerged(17277)]

Playing as Ottomans, Vanilla 1.09. I DoW'd Wallachia, and finished a siege against them. When I DoW'd them, I thought they only had one province. It turned out they also owned Bosnia, so I only had a 14% warscore against them. I also had no access to Bosnia, and bad relations with everyone around it. I decided to try to buy good relations with Hungary and get military access through them to get to Bosnia.

Bosnia, by the way, was controlled by rebels. And while I was waiting around for money to buy good relations with Hungary, these rebels declared independence.

Here's what I'm leading up to: Upon this declaration independence from Wallachia, there was immediately no longer a war between myself and Wallachia. The independence of Bosnia triggered an end to the war between myself and Wallachia.

I thought maybe I had accidentally misclicked and signed a white peace with Wallachia unintentionally. So to make sure this wasn't what happened, I reloaded a game that was at a point just before I finished the siege against Wallachia. I saw that the Rebels already at that point were in control of Bosnia. I sat and waited and didn't touch a thing--just watched. Eventually, Bosnia declared independence from Wallachia, and again, at that very instant, the war between myself and Wallachia no longer existed. My troops in Wallachia had a white flag and Wallachia was in control of the province of Wallachia despite my previous successful siege.

Is this a bug?

Wallachia's government fell. That happens if the rebels control more provinces than the government does -- in your example, 1 to 0. So: all wars are stopped. Any land (except the capital) held by enemies is automatically annexed by them (called turboannexation), and any rebel provinces that could break away into an independent country will do so.

Moral of the story: look before you leap. You need to watch out for this. Sometimes it can be useful but often it can saddle you with a huge number of unwanted provinces and high BB (obviously not in this case, though).
