Restarting as another Civ in the middle of a game

Hi. I was playing as the Germans, when at the beginning of one of my turns, I got a message saying "Are you sure you want to declare war on the Japanese?". That message isn't strange as I occasionally get that message at the beginning of turns (I'm guessing from units on auto explore), but what happened next was weird. I moved my cursor to click on "choose production", when there was a high pitched beep, and the game froze. Then it went to a loading screen of the Japanese, and suddenly I was starting a new game as the Japanese. Ran out of time by this point and had to stop, but it looked to be a new map (can't say for sure though, could of been the same map in a different area) and it went to turn 2 just fine.

Edit: If it helps I had just rushed hospitals and vaccinations in my four cities the previous turn. And it was a version I picked up from steam last week.

Hmm, can't say much about the bug, but it'd be best if you could provide your lua log to see where the bug lies.

In any case though, it's not normal that units on auto-explore move into foreign territory, they should go around them, no? And those movements should be made not at the start of the turn, but at the end, no? It does eem like something's wrong with your game.
