Today, I tested all family who has level 10 in Piano skill. First of all, I will post all screenshots.
I didn't remove any mods or ccs at this moment. This is J sim. His name is Jinwoo, a Korean name, my nationality.
He can play the tunes even though I didn't remove anything. Only different point is that his wife is Zoe Patel from Oasis Springs, Maxis sim.
I was so happy, so I recorded his playing. :D
So beautiful...I love this tune :D He is playing this tune in Roy Winn's house.
Looks like the video doesn't work properly so I brought this from youtube again.
And then, I switched the active family to Roy Winn Family.
Roy is exactly on the same spot where J sim performed serenade for his wife.
Also Roy's wife is in front of him.
I evicted whole Winn family at the managing world and put them back in but still didn't work.
This household is totally different one from J or R families. These guys even don't know about Roy and Jinwoo.
Both of them don't work. I created these sims when ROM was released. So this household is the latest sims I created.
Roy sim was born in 2017, Roy is a very old vampire sim. Jinwoo was born in maybe 2018 as the 2nd generations from his vampire parent sims.
Roy married with Jinwoo's sister. So Roy's wife is not a premade sim by maxis but Jinwoo's wife is.
The guys in the white box cannot perform serenade at all.
Only the guy in red box can do.
Now I just took out all mods folder one more time, then repaired whole game in Origin one more time.
Of course, deleting cache files is regular routine I do before starting the game.
Then I tried again.
They still cannot perform the serenade each other.
Even though, this Louie's violin skill is only level 6, but there's no problem to perform the serenade.
It doesn't work only for PIANO... If the game didn't recognize their relationship, then even this violin and guitar serenade wouldn't be available.
And Also...On piano, even singing serenade wouldn't be available if the game didn't recognize their relationship but singing serenade on piano works.
These guys are the 1st generation in that family tree screenshot above. They have 2 sons and one daughter, and that daughter married with Roy.And One of their son, Jinwoo married with Maxis sim in Oasis Springs.
Over all, Only Jinwoo sim can perform that serenade who has Maxis female sim as a spouse. The others have all my created sim or 2nd generated from this guys and they cannot perform the serenade. But the sim in the video from youtube I posted on the first writing, is Roy. He used to perform the serenade and the woman sim in youtube video is his current wife. But now he cannot do it any more. anywhere in the world.
Here is a question. If the game didn't recognize their all relationship, then why all of them can perform serenade on guitar and on violin? If the game didn't recognize their all relationships, then why all of them can perform 'singing serenade' on Piano? All the instruments were supposed to be inactive but only serenade On PIANO with no vocal(singing) doesn't work.
I feel like maybe the game doesn't recognize their Piano skill level?
