You said for you it never goes away.
- The toddler one is something that got fixed in a patch and there were still reports. To my knowledge this was for the sentiment happening with no reason (the notes for the fix was: Toddlers will no longer gain negative Sentiments against their parents randomly, especially the Festering Grudge Sentiment. I should not be laughing at this issue as I type it, I should not…<giggles>).
- Festering Grudge for any minus friendship: Was about you will get the grudge for just about anything (so a bit excessive)
- Could be what you are reporting. This was in reported in General discussion though and was never reported in the bug forum to my knowledge. It's also unclear to me if it's just too long/frequent for the OP or never got away.
- family Recipe: If that's what you are seeing, please upvote.
- The insulting has an active bug report here: Autonomous Insulting (Patch 1.108.349) | EA Forums - 5018647
- Smooth Apology: Is also an open bug. Just upvote that if you see it or send your save game to EA if you haven't done so.
So from what you reported. 2 or 3 is probably closest. You say it's permanent for you. Does it never go down or just happen easily again that it sounds permanent ?
The toddlers don't have an active bug currently so if you see it for toddlers with no apparent reason, create a separate thread for that.
