I was wondering if this is a bug in the game or if i'm missing something.  In the single player i've played two games where the teams are locked from the start.  Since games take a while I save them and load them up later and everytime after I've loaded those games the teams are no longer locked.  The game started with locked teams but once I load the game I can make alliances and people start giving me missions.  Is there a fix to this or am I missing something or is this just an unfortunate bug in the game?
