Just out of curiousity, can you please answer the following.

Why did you give up Venice? If it rebelled that would be different but to just "GIVE UP" a territory like that seems kinda odd.

Do you have a General in the stack, make him join the crusade and watch as you lose the troops in the stack or at least get a few turns of free upkeep.

The Germans are on a crusade, why aren't they moving at all. Are they blocked as well?

Could you retake Venice?
