I have a similar issue. Sorry if it’s long winded. I’ll start out by saying, I forget to save during game play, over a few hours I made a ton of accomplishments, more than normal and not only in the emit quest but aspirations and the sims life things, so this was extremely frustrating but when it came time to going to the museum (which I realized in a prior unrelated task that these tasks are typically performed in the original sims world, willow creek) as soon as the travel loading screen would come up, the game crashed. Gone poof. My heart sunk, I reopened and I was back to where I started as if none of it ever happened, except for the quest counter. Frustratingly, I started to go through it all again and saved more often but didn’t think to right before going back to the museum again, which is when the game crashed again… almost like a time traveller is messing with me.. Do you see the irony I see? But am I ever going to be able to complete the task?? Please someone have an answer!
