This has been reported before, but if you still need examples of this happening under 1.12.369.210, I have included a link to a save file here:

https://www.dropbox.com/s/k76oi3e0bzohmgp/Freeze%20On%20Altarians%20Under%201.12.369210.GC4Sav?dl=0

To recreate the issue:

1. Load the above save
2. Hit the icon to go to the next turn
3. Say "Yes" when prompted about attacking the anomoly
4. When the Battle Report appears, just close it
5. The AIs will start taking their turns and the game will get stuck on the Altarian's turn

I hope you are working on fixing this bug because the only thing I can do is abandon this game and start another one.  I believe this is the type of bug that will seriously impact the quality image of the product if it is still in the next release.
