In a sticky situation - Pope has declared crusade on my vassal

[Horatius]

LOL fair enough, I just wasn't sure if I was allowed to break a vassal relationship or not. I suppose I'll take a bit of a hit to my reputation by turning on my vassal?

Or just break the vassalage right before you besiege Grenada, and the second those pesky frenchmen come to call feel free to mock them by taking Grenada in front of them.

Declare your own crusade against your vassal...Hire a few crusader units even if you are going to use another stack on the settlement. That way you get a few good units for a cheap and quick buck.

I also disagree that it's a good idea to take settlements if there's another crusader army in your territory. Given the nature of the AI it's just an invitation to attack. XD
