So some people say their game has been updated in the last 9 hours or so. So has a second patch been released? I've seen no news on this.

No there isnt any updates.

The update the people saw, was for deleting language files in import versions.

My game was in german and now i can choose only English, Russian etc., but no German anymore.

This was the last time i bought an ID Game.

WTF? Didn't notice that. Can anyone confirm this? Where did you buy it, in England?
I'll have to check this later myself. I'm German too, but yet played in English. Would have liked to check out the german translation later, though :/
