I experienced a major, freakish, gamebreaking bug. 

What happened:

I'm playing on a tiny map on turn 205 and with an army consisting of my sov and 5 other units I attack a city and choose 'battle'. I win comfortably, but the result screen shows that all my units apart from my sov have died. When I click the result screen away, the game runs off by itself: I immediately get another battle screen saying my enemies attacked. I now batlle this out with my sole sov and win. After clicking the result screen away I get another battle screen saying a caravan somewhere has been attacked. I choose auto resolve, the caravan is lost and I immediately get the research breakthrough screen. After that battles screens and tech choosing screens just pop up after one and other. I can only click on battle/auto resolve or choos the tech, but cannot select a unit, city or anything. Meanwhile, while these battle/tech screens are open, I see in the background that the game progresses very quickly. 

I tried loading the savegame multiple times, and although sometimes the battle outcome screen after the city attack would be right, the game always runs off by itself as described above. Pastebin wouldn't let me upload the debug.err or the savefile, saying they are too big, even when I zipped them. If you need these files to adress the problem, please let me know if there is another uploading device that might work.

I don't know if this type of problem has been reported already, but I certainly hope there is a way to solve this...
