I think this had to do with that I loaded a save that was from a previous version. I restarted the map and at month 2 (I think) the red player attacked my city.
im sorry pal, but you're screwed. unless you restore the previous version for the rest of that game ( which im not so sure will work) you'll have to restart. once my friend was playing the first mission of "the necromancer" and one of the wizards were in his way (wouldn't move) and there was no other way than to restart. sorry
