I'm having a similar but slightly different issue.
I have a tombstone with a ghost Sim still attached to it and my Sims have been offering sugar skulls at night but the interaction fails every time. They offer the skull, nothing happens, they start begging and pleading, then sag their shoulders as if they're disappointed it didn't work. I get no notification that a Day of the Dead Celebrator has arrived or anything. This happens consistently 100% of the time no matter what.
I thought it might be because the dead Sim is my Sim's ex-husband and was enemies with my Sim and her current husband when he was alive. So I had her current husband become good friends with his ghost but he still can't successfully offer a sugar skull.
The dead Sim is a vampire who died by sunlight. I don't know if that matters.
P.S: I just realized this thread is over 3 years old. My apologies, I didn't mean to bump up a dead thread. I was just googling for answers to my problem and this was one of the first results that sounded closest to the issue I was having, so I assumed it was recent.
This is super frustrating and I havent been able to find any solutions either. I'm able to do everything up until the actual point of receiving the skull. I have maxed friendship and romance, as well as BFF status but every time I receive the response " why would i celebrate the day of the dead with a stranger or enemy?".
Any pointers? I've run out of new story content a long time ago so I was really looking forward to something 'new to me' when I realized. From what I see online so far its to be assumed this content is essentially abandoned and quite broken?
