just going to +1 this thread for visibility. 1000 hours into the game and I get this all the time. this is a Steam problem, not an eu4 problem. when the problem occurs you can click the screen and it will go white, meaning the program is "not responding" according to windows. and if you alt-tab to steam, steam's friend list (and any other steam window) is also white, meaning "not responding" either. is there any chance to make ironman -not- use steam cloud, as the cloud is extremely unreliable for some people? the game does continue on if you wait the 2-3 minutes for steam to respond but this happens very frequently, and I am frustrated to the brim trying to play ironman mode with this problem.
