Sorry I dont know how to find out what server and gameId but presumably there is a way by looking at the time of this post vs my last game (ie. around 10:20am).
After buying the last province and ending my turn the game didnt end or goto the normal summary of scoring page.
I had played a crypt and horn of plenty (to get one of the provinces) just before the game ended if that is helpful.
eventually i refreshed on the browser and it brought me back to the main login screen
There was a general problem at around the time you posted this that had the effect you described on some games. Tomorrow will be downtime to address some of the instability that has crept up in the last few days.
