@Pinar2306 Haven't seen this posted for a while! Here's the note from the Master Post pinned in this forum:
Food stall and Festival vendors sell only produce – causes include outdated custom food stalls, outdated playable NPC career mod. NOTE: Althought this is an old issue and you're unlikely to currently have outdated custom food stalls, if you do get this error, delete the stalls before saving; outdated custom food stalls have been known to cause save corruption.
@Pinar2306 It's not all the vendor stalls you'd be deleting, only custom ones that you had mods for, and then you'd remove the mods. But there's a chance that if you can't get those mods anymore, this isn't a recoverable save... for which my condolences. I've done this move to a new save and it's not fun. FWIW, I use a combination of MC Command Center, the Club system, and UI Cheats to reset inter-household relationships.
