I said I would go back into my game and see what happened. As I said, I saved before the party and didn't save when the freeze happened, so I loaded the save from before the party.
My Sim threw the same type of party, with the same guest (I think) but of course different party goals, I had no influence on that. Anyway, my game didn't freeze! 🙂 I have played, I think, another Sim week or so and everything went smoothly. So, I kind of feel like I have found a sort of work around that works for my game/my computer (I am nevertheless knocking on wood).
I can't say it will work for everyone (it probably won't), since I remember my old computer reacting somewhat differently. Maybe someone has already mentioned this, I haven't read the entire thread, I've only been actively monitoring this bug since it started happening on my new computer. I also don't know if it will work in the long run, but for now the following has worked for me:
- Start a new save game, save often, like, at least every Sim day so you won't lose too much progress. Be sure to "Save as..." the first time!
- The moment the freeze occurs for the first time, try to sit it out (I haven't tried this yet (and hope I won't need to), not sure if it actually crashes my game by default or if it were my actions that caused it to crash).
- Then exit the entire game without saving.
- Repair the game in Origin.
- Write about your exact experiences in this thread (that's what I've done anyway, not an obligatory step of course), or submit a video, screenshot or the autosave (if that has saved the game after the bug occured).
- Restart the game, load your original save, not the autosave!
- Continue playing and save often.
No idea if this works for others, it has worked for me in one instance. If anyone wants me to, I could test it with the other save game that I didn't save when it froze earlier this week.
I think, and I am speculating here, the key is to keep your game "freeze-free", so never save once it occurs, and always repair the game before going back in. I think that once you've had a freeze and saved, it will keep happening.
On a side note, my computer has pretty high specs, well above the recommended specs. I can't imagine this working on my old laptop which was just above minimum specs. I see a noticable difference between the two - on my current pc a freeze hits and it hits hard; on my old laptop it sort of seeped in, tiny (barely noticable) freezes at first which later on become bigger and more frequent - I think it is a lot harder to keep good track of them in that situation. But that's just my experience so far.
I really hope this helps people - I know it's far from ideal, but if it keeps your game freeze-free for some time, I think it may be worth the effort.
