I did not call the crusade.I was told there was a crusade by Norway and already ask the admins to confirm if it was called by the pope.Although if it is true that the crusade was called then i believe Moors broke this rule:
Once a Crusade/Jihad target is named, you cannot:
-Assasinate the Pope (valid for any faction) until the crusade ends.

That too would be for the admins to confirm.
