The game wont save correctly. When I start a skirmish, I get the 3 autosaves, (I think) and maybe one manual save. Then it seems to just not save. I also tried writting over a saved game, and when I went back in there was no save game. I had deleted all saves except for one, tried over writing it and when I went back to load, there wasnt any save game. So when I saved overtop an existing file, it lost the save file, but never wrote the new save file?  It may be related to size of save? The first 3 autosaves are soon after starting, At some point it stops saving. I noticed it when I tried to save a large map with lots of units.  I uninstalled and reinstalled.. No change. I have no saves now and will try starting a new skirmish and see if it acts the same way.

UPDATE Same thing, I try to save, wont save and if I say over write this file, it loses original file, and doesnt create the new file with same name.  ITs the size of the save. I saved fine early in game. Now cant save, never got any autosaves, I have 17K units and 4 AIs still alive. so it is the SIZE of the save, or number of units, etc.. But it is a BUG. Cant save a game that specifically says massive armies etc, and you cant save the game after you build massive armies.

Also had some movement issues, but the Army may have been full?  It showed them as part of the army, but a group of units wouldnt respond to army orders, I had to manually select those units and tell them to join thier friends.. Once they were with army they were fine.

Also been having the crashes at the end of game when I have a huge army. Its all related to the game not handling huge armies, thats a fail.. umm I think it started with 2.2 but I cant say for sure.
