When I was having a lot of Code 12 problems with my "legacy" family, I tried deleting items from their household (as I had had them buy things every time they got the wish for it.) I tried deleting things I had saved in CAS. I tried deleting all the cache files and the DBtravel file. I tried moving them to a different neighborhood by putting the family in the library, then putting them in the new neighborhood (which is supposed to really cut down on the size of the file). I made sure that everything was closed on my computer before starting up the game. I made sure that I deactivated the "memory" in the game, and deleted everything from their memory that had already accumulated.
However, none of that worked. I finally got so frustrated about the crashing to desktop and Code 12 (even though I was saving more than just every simday) and not being able to travel that I just started over. It was the only thing that finally worked. The new game has not been a problem.
I don't know if it will work for error code 12, but one thing I do that's drastically cut down on the file corruption is rename my save file at least once per gaming session. Just use "save as" and add 1,2,3, etc. to the end of your save name. This gives you a fresh file to work with without having to start a new game. I used to get error code 16 a lot with WA, but haven't had it once since I started doing that. Other problems, like the broken travel world (arriving at your destination without your sim) also hasn't happened since. Just make sure to delete the old saves, and continue to clear your cache files after each playing session. Also try Nraas Overwatch mod, which helps clean up your game.
