In my last game (it was Talos Lord of the Rings Scenario) everything started as usually. Player choose their countrys and then the first turn started. Every Player could just build Militia. To be able to build other units I had to move the units in the city away and then cancel the move, but without this trick i was just able to build Militia.
I thought ok, if this is the only handicap then I can still play. So did I. Some people already left at this time. Then when week 2 started I first got some error messages (sorry just have 1 ss of it)

After this I just clicked ok on this error messages in the thought the game would still work, but then when i wanted to click on a city to reinforce it. I got this:

At the same time Cthulhu got also some exceptions, although he was just a spectator!!!

If this happens again. I will try to get more details, but maybe this already helps you.
