Hey, so I am not sure if this is the right place for this question or whether any of you can actually answer it. Here goes, though.
I am currently playing as game as Novgorod and I am currently incapable of declaring war on anyone. The game is telling me that a special game rule is in force which is not allowing me to declare war. I only have three trade routes and they are only to one civ so I can understand not being able to attack them.
The real kicker is that I don't think that any of the other civs can declare war either. I am going to play the gamer further (I am only in 100 turns on quick) to find out, but usually a few wars would have exploded by now.
I am running these new civilizations alongside the CP, CBP, CSD, Civ IV Dip, E&D, More Luxes, and EUI. I am not sure if there is a new incompatibility with CBP seeing as Gazebo is updating it rather frequently.
Sorry to be so long winded. Cheers!
