How to remove custom food w/o corrupting my save?

lambcaey​ Have you tried a "save as" after removing them? Also when does the error code appear? Removing these mods shouldn't block anything except loading a household that has food still in it. 

Yes. I made a "save as" before then closing the game, and removing my custom food mods. The error plays any time I try to load my main household on their home lot. They can visit anywhere, but going to their house, or even moving to a different one, brings up the error code.

I read about the error being caused by custom food plates, so I bulldozed the entire lot in advance, and even emptied out the inventory of each Sim; still got the error code.

If you save the household to your Library and reload them in game, are they fixed?

Only if I start a whole new game with that household. Otherwise, I have to recover an older save with the custom food mods in.

I'm doing a decades challenge, so starting a new game would remove all the genealogy of that household.

Do a Save As after all the removals of mods, not before. See if that helps.

What good would that do if I still get the error code? Wouldn't that just be doing a "save as" for a corrupted save?

Not trying to argue or anything. I'm just concerned about not being able to recover an older save.

lambcaey​ The reason you're doing a "save as" is to clear things that are leftover after the mod and all the food associated with it are gone. If the mod is still there, a "save as" is made with that mod installed.

It's one thing to try.

Welp, the latest update disabled all my mods, but I didn't get the error code! :D

Thanks for your advice. ^^
