I loaded my previously manually saved game that I got a CTD, and played for like 10 turns.
I got my sovereign to zero hp so he was regaining hp in my city. I wasn't doing anything other than building huts. not even using ui subscreens. I was just mashing the end of turn button waiting for huts, and hp, and it got stuck.
I saved the game.
I went to the main menu and clicked new game. The new game panel did come up.
I went back to the main menu
I clicked exit.
The game did exit but I got and "Application stopped working" message in my desktop.
