Stuck on household loading screen I have this problem since I've installed Seasons (or alternativly since I've installed the Happy Holiday Stuff Pack, I did that in one go). When I load the household I get the usual loading screen, but once it is fully loaded the hourglass doesn't disappear, but keeps turning, without anything happening. I have to shut the game down via the task manager to get out of it. This does not apply to all households. Apparently at random, since the ones that are broken have (at least from what I remember) nothing in common that would differentiate them from the working ones. Turning Custum content off changes nothing. Also, I have installed no custum content since installing Seasons.
You haven't listed your computer specs, but it sounds like it may be that the game overloads your computer on some of the lots. That was a common problem with Seasons, which is very computer hogging. It's especially bad if you happen to have any of the ladybug houses on the lot. Even a single one can mess things up. (It's better to have all your gardening done inside of a greenhouse.) Also, there was a mod at MATY which muted the ladybug house problem.
