Alt-tab caused game loss

[GlobularFoody]

I was just playing as Korea, game was running normally, then I alt-tabbed and it brought up the end game screen and I lost. On the Hall of Fame screen, it's just listed as a loss and no winner. Is this a new bug with the Korea DLC? I've played tons of games and never seen this before.

Here's a pic of the HoF screen.

Alt tab is the new retirement option??
