I'm having a terrible time with this...

1.) Sending a crusade from England through northern france. This is a very bottlenecked area, with trees, hills, etc. Unless I move them 1 tile at a time, they inevitably run into a red zone and stall.

2.) I move my princess up north through spain. She gets blocked by Pamplona. Fair enough, but then I get a Relationship worsened - Portugal = Abysmal. WHA!?!?
