Um, I still don't know who logged in as "AmateurPain", but since I could see from the score that no city was built I thought it would be best for ProPain to kick him, so that the AI can finish his turn and build a city. When I kicked him, the score still didn't increase, so apparently the settlers just moved. Now in the new turn a new city actually is built, by the AI.
So in retrospective it probably wasn't a good decision to kick him. Anyway, a new turn started. But if Mongolia is made a mess ProPain may demand a restart IMO.
But
who logged in for ProPain?!
