yeah if the cpu issue has been around for a year i've never encountered it, my game only crashes when i have mods installed. i let a completely clean save run in from a fresh /documents/electronic arts/the sims 4 folder again and it ran for over an hour without issue, but as soon as i started testing with mods again the crashing started back up.
i think i might have isolated the mod/mods responsible but i haven't tested a fresh save without it yet cuz at this point im a little discouraged and dont wanna get my hopes up again :\
edit: nope, just crashed again.
