Game Keeps Crashing

SrgtMarsmallow​  The crashes in your dxdiag aren't that informative, which wouldn't be surprising if the problem were the game, specifically the lots you were playing on.  The Watering Hole seems to have issues, as do the other pond lot and the treehouse lot and perhaps the entire Sprucederry neighborhood (the upper-right one).

So if you can replicate a crash on the Watering Hole lot, or any of the above, I'd like to have a lastcrash file.  It would be in Documents > Electronic Arts > The Sims 4, and I'd only want the most recent one.  This would be to pass on to EA; I can't use most of the file's information.

If you do get another crash on an Innisgreen lot, and you have a lastcrash file to go with it, please delete the file's first line, then attach it to your reply as you did with your dxdiag.  Or you can copy and paste the text, but this site sometimes flags such posts as spam.  So if your post disappears, report the thread and say so, and a community manager should be able to restore it.

Point is, this is the info that EA can use to try to diagnose these crashes, along with your dxdiag that confirms there's no obvious system issue.

I'm not sure why the game crashed in Sulani, but if it only happened once, and it doesn't again, it's probably not worth looking into.  If it does happen again, please let me know what lot you're playing on and exactly what you and your sims were doing at the time, and also what time of day it was within the game.
