Oh oh, I'm being abused by Cainehill.
Seriously, I could not get in for several days, and when I did (thanks to the advice here), there was nothing left of me. I did not go AI until I reviewed the situation, believe me...
I will generally be in for the long haul, but I had few provinces left, few troops, dead God, blood economy in tatters (which was my first time doing a blood economy), capital under seige, etc..
But my apologies Cainehill, this is not an action I would normally take.
