@mountainlions123 Okay, then I'd start by adding NRaas ErrorTrap, Overwatch, and MasterController. The first two run various cleanup routines on their own, without any need for player intervention; MC doesn't do anything unless you use it to issue a command. In case you're not familiar, here's how to install mods:

With the three in place, try running an MC Town Reset: click on City Hall, select NRaas > MasterController > Town Options > Reset Everything. The command can take a few minutes to run, depending on the state of the save and the speed of your hardware. This will also reset your active sims, so be prepared for that; you can disable the reset for the active household in MC settings, but at this point, it's better to be thorough.
Once the town reset has finished, let the game clock run for a few minutes, then try using "save as" to rename the save. If it works, quit, delete the five cache files in your user folder, reload, and see how the save plays going forward. For reference, the cache files are:
- CASPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package
If you can't save your progress, or the save doesn't load at all, let me know. There are still a few tricks to try, plus if you get any scripterrors in your Sims 3 user folder, they're worth reading. For those, you'd need to post on the NRaas site, where the mods are still fully supported and people can read the logs; my interpretation skills are rudimentary at best. And just to be clear, you almost certainly will get at least a couple scripterrors, because ET lists the actions it takes, but many of those are just routine cleanup and can be ignored unless your save is displaying symptoms of corruption.
