Re: Sims 3 64-bit crashing every 15 minutes
@amymar17 If you're willing to add another NRaas mod, try using Register to disallow stray pets and wild animals. Click on City Hall and select NRaas > Register > Animal Control, and you'll see a number for each type of animal, excluding small pets. It's possible that strays are contributing to the crashing issues, and this is an easy test.
If you're fond of one or two certain strays, you can try only zeroing out the other animal populations that don't include that type, e.g. if you like a certain cat, leave that population number as is and get rid of the others. You can also try this on a spare copy of your save if you're not sure you'd want to play this way going forward. Use "save as" to rename the save, and the original will remain intact while you play with the spare copy.
