A friend and I started a MP session today, with V 0.99. We loaded a saved game from last week 0.95. We got only part way through the Terran Alliance turn when the game froze on me and I could not hit the arrow to advance the turn. I could exit to the main menu. We tried this 3 times. I even saved part way through the turn, but the same freeze happened, even after re-loading the new saved game.
I noticed that my Gaze ship had no icon showing - only a black box - in the fleet display at lower left.
In one instance, we had the Terran Alliance symbol at bottom right, next to the turn arrow, but no wording "Terran Alliance".
I can provide a saved game via dropbox.
