Can't Open A Save for the Past 2-3 Months; Error Code

Could you perhaps try moving the mods folder to another place, then go into the game, try changing their outfits in cas in manage households. then save the game under a new name for testing. Come out of the game, clear the cache files, then  go back into the game, load the test save game and see if the issue remains. 

I've tried a couple of times, I'm afraid it doesn't work, it doesn't load into the save. :(rosemow​ 

Are you unable to load the save that your legacy family is in, but can load other saves? Or can you load that save, but not that particular household in the save? 

It's only that save, I can't open any household nor add a new one when I have mods in. When I take mods out I can open other households, add a new household, but still can't open my main one. I can load other saves, I haven't had problems with them yet.

It sounds like it could be a mods/cc issue if you are unable to load other households in the save when you have mods in the save. You may need to test to see what mods/cc are causing the issue with the other households. Make sure that every time that you remove the mods folder when testing, that you also delete the localthumbcache.package also.

I have tried it all, I'm going to keep trying but it seems unsolvable lol, still thank you though 😊
