Re: Sims 3 into the future crashing and closing game
@saffyronny Repairing doesn't affect expansion packs, that's true, but it's unlikely that this is an issue with the game data. Sims 3 travel transitions are fragile and often break, although crashing is less common.
One thing worth trying is enabling object hiding. It fixes the red flashing that many of us see elsewhere in-game, and I do remember that I've seen red flashing when the future world loads, so it's possible that could help.
Otherwise, do you use mods, or are you willing to try a few? If so, I'd suggest adding NRaas Traveler, which replaces the travel transition with a more stable version, as well as ErrorTrap and Overwatch. You can find more info on them here:
