Re: Error code 12 and crashing
@riahbearrr Error 12 is an out of resources condition, usually but not always related to the game's memory use. No matter how much RAM you have installed, Sims 3 can only use ~3.7 GB (4 minus some overhead) because it's a 32-bit app. After that, it will crash or throw an Error 12, depending on the circumstances. This limit cannot be overcome.
Storage has nothing to do with this, although your 1 TB SSD is undoubtedly useful for other reasons. It should also not take 20 minutes for your save to load, at least not with an SSD and other good hardware. For comparison's sake, how long does it take to load a new save in Oceanview for the first time? How about the second time? Please test and let me know, and also test Sunset Valley, both a new save and one you've saved once and reloaded, and let me know what kind of load times you get.
The reason I ask is that your current save may be corrupted, or it might be that something else is going on contributing to both the long load times and the crashing. So the first step is to narrow things down a bit.
