GA's do seem to be a little buggy at times. Its odd that the Italians asked you to do this. When playing as the Spanish I launched a crusade to Morocco on the popes behest. However a french crusade got there one turn before me. I got the message that since the province now was under the control of good catholics the crusade was disbanding. I think my king took a hit of a point of influence due to this.

Didz, when you say you got a successful message, do you mean a successful conquered the province message or a successful crusade complete one. If any enemy are under siege then the crusade is not counted as complete.\

On the subject of GA's I've noticed that conquered province points don't seem to add on correctly. AS the Danes, I'm supposed to get 2 GA's for every province I conquer and because I've been a busy boy, all my pips are red. I should be getting about 32 GA points (including homelands). however the Byz. who have just sat on their arses are getting far more than my self even though they are just defending homelands. I do realise that they get quite a few for this but I ought to be a long way out in front because I own almost all of northern Europe. Otherwise how is it possible for a faction such as the Danes who get pathetic homeland points to win short of eliminating all other factions. If I wanted to do that I would have selected conquest mode.
