So after some testing, I found that it's the it's complicated rel bit that prevents them from woohooing.
I have no clue why that is tbh but I'll need to do some more testing with other Sims if adding that bit does the same for all Sims or if there's other factors.
EDIT: So it does seem that the rel bit doesn't let them woohoo but I wonder if it should have gone away once you leveled back up. Did you use any cheats to get them back up in their relationship ?
Could the complicated relationship thing be that Kaori asked my sim to prom once but I said no?
I didn't use any cheats on their relationship. I did cheat two other sims' relationships but none with the members of the active household.
I don't know all the details how you get it but it's possible. Also don't know how you can get rid of it other than using a mod.
Putting this on review as it def seems off.
