When I published my first game, I wasn't prepared to have a pic ready (I know, small deal, but), so I just threw something up there. Anyway, today, I changed my picture for my game, but it doesn't appear to be showing the new picture. It's been a few hours since I changed the picture (I figured I'd wait a bit to see if there was a bit of a delay). So, what's the deal? Does it take longer (like a day) to update?
