OK, I got finished Annu campaign on Hero. Since its very exhausting to start things over, I through continuation of campaign before the Palace mission, just for the other side, would speed things up. Did a lot for NJ, reaching diplomacy 100, Project Nemesis was researched, Fortress has been built but “Plan did not appear”. I did not research Injector to prevent loss of diplomacy.
So, can more then one side “Palace” mission exist within same game, or which we reach before? I have saved and researched Injector, obviously PP plus one side (hereby Annu) can exist and you can pick which you like, but I am asking for e.g. NJ and Annu Palace missions?
