Family Fortune: Clear Negative Sentiments not Completing (Patch 1.109.207)

Finally got all three siblings (plus Grandma) to have positive sentiments with each other and still can't get past Healing Negative Sentiments. Anyone, please, help? 

Mine is like this too. Grandma had no relation in the Family Tree but shows that they are her grandchildren in CAS. Same with the siblings; in the Tree, there is no connection line showing they're siblings. 

I have the same problem.

I can't get past the remove negative sentiments part on the scenario, the sentiments are not there but it doesn't register as having been removed. As of August 4 2025 this bug is still ongoing. I tried all the workarounds suggested (besides mods) but it still doesn't work.

I have the exact same problem, my sims all are friends with each other, have only positive sentiments but the "heal negative sentiments" isn't working.

I made the original post, mine is still not complete.  I still have the incomplete scenario in my legacy save. I have over 300 sims I play. I can send it if needed. I play with no cas or bb mods. Just a script mod, that command centre one, as advised.

recar2 is your scenario completed yet?
