[CL] Can't play duets with household members

ok thank you. I can imagine how busy you are so I will be patient. I have probably 1000 hours in my main game and I just can't fathom losing it all. I did find one thing I should mention for full disclosure. I didn't think it mattered because I almost immediately removed it and this was well prior to any problems. I installed a mod called **bleep** but it was deleted almost immediately because it was totally not what I was after. This morning when I was restoring my saves I actually went into the save folder for some reason, and all my saves were there but there was a folder as well and it was for that mod. I didn't know it was in there, but, as I said, everything worked after I uninstalled it. So I saw no reason to mention it until I saw this folder. I did not put it back into the game save folder with my saves, but I didn't delete it from my backup yet in case it might be needed for some reason. Its settings profile only references one of my saves back on May 9th. Let me know if there is anything you need from me at any point and I will gladly get you what you need. 

I fixed this problem. I did two things and should have tested after each but I wasn't thinking because they were sort of related but not entirely.

I had found a Sulani Super Yacht in the gallery when I was trying to fit something in the large empty water lot in Sulani. My intention was to purchase it as a vacation home using  LittleMsSams mod More Buyable Venues and New Venue types. Once I did my sims could not take an actual vacation to go there. So that rather ruined that for me. So I decided to turn it into a vacation rental but the lot was designated as a special venue and I couldn't do anything. So I found a mod called Venue changes made by Zerbu and finally was able to change the lot type. At some point during this I had my sim sell it because I wasn't interested in them owning a vacation rental. Once it was done I rented it out and tried to start a social event to throw a party and it was not possible so I was over it and just left it figuring I might use it at some point. Since my sim sold it, I'm not sure this had anything to do with the karaoke problem. 

So part two is this, and I feel like this is what was causing the problem. There is a residential rental in Henford-on-Bagley, 13 Nettle Lane, that I had taken my sim to for a vacation once and he met some foxes and befriended them. So I decided to buy that vacation rental as a holiday home. To do this using More Buyable Venues and New Venue types I had to go change the lot type to generic and then I was able to buy it. But it was strange as it was listed as a business and people kept just walking in and stuff and I was like ughhh. So I did some decorating and left and hadn't done or decided what I was going to do with it since. 

Something was bugging me about this so I went to Sulani and bulldozed the super yacht. Mainly because of a post I read about game saves and large houses with lots of items. Then I took my sim to the lot in Henford and transferred his money back to the household, sold the lot and then went back in to buy build and changed the lot type back to residential rental, saved and went back to my sim's home. Took him and his wife to Planet Honeypop and they were able to sing duets together again. Took them home and went to my other main household and did the same and they too were successful. 

So this seems to have been the "what caused" the problem. Just no clue on the why. I am not going to reinstall those two mods I mentioned as nothing worked out how I wanted it to anyway. But I a going to go in and purchase something using only the means the game gives me and see if the problem reoccurs and I will let you know.

I know you had the problem in one of your saves and if you ever figure it out I would love to know what you find.
