As in crashing, without warning.
I thought it was my Sims themselves that may be causing the problem, as they are the original Sims I first starting playing from the beginning - eight years ago. Then I got a new computer with Win 10; Sims 3 installed and ran fine, but after all these years, I concluded my original Sims were just too corrupt to continue playing. So I decided to revisit old saves from years ago, as in 2012 - before Seasons and Supernatural were released. I noticed the redraw time was far less on the old games, so I figured great, I'll just play these again - relive old times. Nope. A simple trip to the public pool or even just doing some redecorating in edit mode and the game crashes, without warning. This is back when I did not have more than 8 Sims per household. I know I could try creating my Sims all over again and see what happens, but I'd rather not go through that. And with no hint of Sims 5 in the near future, I'm worried I may have to return to games like Doom or Wolfenstein. They're good games, but I prefer Sims 3.
