I haven't seen anyone post about this and I didn't see it mentioned in the 1.2 fixes but I get this everytime I load a saved game. The ships will be loaded with the correct amount of movepoints left and then I hit the turn button and all the ships on autopilot with m/p left will move. But the date at the top does not increase and no research or production, unless i buy something so its build time is 0, is done. All the m/p of each ship are then reset and I can move my ships again. Only after I hit the turn button a second time will the turn number actually advance and perform research and production.

I have used this to effectively explore everything within my range and find a nice planet settle without advancing to the next turn, which I'll admit isn't very fun since it feels like cheating, which it is.
