I just started my first game, having bought SoaSE:Trinity. (On that note, it's slightly confusing which game you should start with - I eventually started a new game under the menu that read "Trinity".)
It's a singleplayer game with one other AI opponent, but the game won't let me save. It's autosaving all the time, but Menu>Save>the Save button is greyed out.
Any ideas?
