The sims 3 game crash!

[cruiseship]

Hello everyone! I have the sims 3 with all expansions and stuff packs. I have a high-end pc an intel core I7 with 16 GB of RAM and Nvidia GeForce 1050 video card. This happens to me: when I try to remove diplomas from the walls the game crashes and I also get errors 12. Please, I would like to understand how to recover ... I play with Ellacharmed's fixed worlds! Thank you!!

@cruiseship  You've already received answers to both your questions, several in fact, on the NRaas site.  No one on this site is going to be able to give you better advice than Chain_Reaction already has, and that's probably true for any site that still deals with Sims 3 issues.
