Re: Loading screen stuck returning from university
@Luciaaafs I tried everything I could think of to get the save to load, on two different computers, and I'm sorry to say that I came up empty. The game got stuck loading Riverview each time, with the Task Manager reporting that Sims 3's memory use was stuck at exactly the same value after a short burst of activity. So it's reasonably clear that the game is waiting to be able to do something that it can't.
I do have two suggestions for you. One is to clean the TravelDB.package with a save cleaning tool. It's quite large, in fact large enough to possibly be a problem all by itself, and I noticed in a couple of tests that the game was having trouble copying all that data to the CurrentGame folder. That's not to say that this is definitely the problem—it could just be a side effect of the loading getting stuck—but it's worth trying.
The other suggestion, if the save cleaner doesn't help, is to travel your main sim to another world, specifically a residential one rather than a vacation world. Once there, you could try using NRaas MasterController's Add Sim function to add the other family members from the homeworld to a house or empty lot in the new world. They'll lose their house and family inventory, but the sims themselves should be intact. Add Sim allows you to filter by homeworld when selecting the sims.
Out of curiosity, are you sure those eight packs you listed are the only active expansions in your save? Are you using any non-NRaas mods? The reason I ask is because I saw quite a lot of scripterrors, I think more than I've ever seen at once in a save, and I didn't recognize most of the errors. Some mods can't be safely removed, and expansions definitely cannot be removed without corrupting the save and the sims in it.
