Please use this thread going forward: Exchange Vows Grayed Out on wedding arch | EA Forums - 4990453
Experienced this too now with 2 different weddings held several weeks in game time apart. Wedding events planned on wedding venue lot (BG and dont own MWS). Arch shows "get married.. " greyed out. And it was the same when both just came to the venue and clicked on the arch and "plan wedding event" is greyed with the same missing partner message. I will add that the fiances were in separate unplayed households. I've never tried to test it with fiances being in the same house before getting married though. I see it's a 3 year old bug but I thought I'd me too anyway.
I am also now having this issue. The exchange vows is greyed out saying finance is not on the lot (they were both there and standing next to the arch).
I thought it was cause one was a teen so I aged them up. Nope. Removed one of the sims from family and then it wasn't greyed out anymore, but they "fiance" kept trying to leave the lot and the exchange vows interaction wasn't popping up for the one left in the household, despite being clicked.
I then used the control sim mod to control the non-household fiance and all the options were greyed out for him even though when he was in the household, the only one not showing was the exchange vows.
I have a lot of mods but prior to the new patch, I have never had that issue.
At least the sims sit in their seats now (mostly) 😅
I'm having the exact same issue! prior to this patch, weddings mostly worked for me but now I can't even make them exchange vows because it keeps saying the fiance isn't around
