Curious O.o
Yes and no. The site got moved to a new server. This *shouldn't* affect the game, at least not in theory. It could be a problem on the ad's end.
I know this probably isn't the answer you're looking for, but Premium supporters ($1/month) get served an ad-less version of the game so they shouldn't have this problem. Either way, this sounds unacceptable, but this is the first I've heard of it. I'll keep my ear to the streets for similar reports! Thanks!!!
