[MWS] Wedding Event UI menu blank when trying to marry Special NPC

I'm having this issue as well, except neither of my Sims are "special" Sims...they are both ghosts though. I'm trying to do a Vow Renewal and I'm not able to because I get the same menu screen as everyone else has described.

I haven't been able to throw a wedding; the UI for it is messed up. I don't have any mods or CC installed. An important note would be that I am trying to marry the Plumbird. I don't know if this bug is because of that or something else. Any help?

Hi. Same thing is happening to me, where the wedding event page appears blank. However, I'm trying to marry Sienna Grove from the Horse Ranch EP. Anyone know how to solve? 🥲

Interestingly, when I clicked on Grim to plan the event instead of my ghost Sim, this menu popped up  

Then I went back to my ghost Sim, and the same menu appeared - was not blank anymore. But it is missing all other related wedding events.

Same for me - I had Grim Reaper propose to my ghost Sim, and cannot plan the wedding

Also tried to marry Emit. Had the same glitch.  Posted details here: Bug - Marrying Emit - Lot's of glitches, but this last may have broken my save! | EA Forums - 11929995  by accident. 

The non-custom wedding got me to the wedding, but Emitt immediately left and my game was kind of soft locked >,< My sim could not escape the wedding. Quit the gam and came back in a few times, was stuck for a while, then rebooted the whole machine, not just the game and EA app. That brought me back to a if the wedding never happened. So at least I was free. Managed to elope. (for those wondering he doesn't have any special traits that I have noticed and his kids so far don't either. Ah well) Not sure what will happen with him after the event finishes. >.<()

Don't know how to edit. But closed out again fully rebooted, reloaded the game and my sim is in the wedding venue, but the wedding event is just... gone. Taking it as a win, but leaving the report here in case anyone else is having this issue, and because of the other parts of the issue. (like the dates breaking)

Playing on a Mac running Sequoia 15.3.1, just downloaded the update that dropped today (Feb 25).

So I have one family I have been using for all the new sign in challenges and I remembered that there is a special trait kids born from Father Winter could have, wondered if Emit's kids would have any interesting trait and if he could be married and brought into household. The whole "romance" was glitchy, with some options appearing and then vanishing, and then Emit refusing any romantic interactions despite having a quarter full pink romance meter. Then I got beguiling for the sim and suddenly he accepted romantic interactions. Perfect. Except that any time the sims went on a date (he invited him once, he invited her once) the date ended abruptly after about a minute. 

Also he kept just abruptly leaving with no apparent reason whenever he was visiting.

Finally got him to agree to a proposal. Tried to do the custom wedding. The screen to set it up popped up but the categories were blank. Wish I had thought to screen shot it. When it had that issue, I saved off, closed out and came back in. Same issue. So I did the regular wedding. All the sims arrived. I sent my sim to kiss Emit. He didn't allow it and just walked off the lot. I then got stuck in the wedding. I hit end early and it said that I got a bronze medal, but the event was still going. My sim couldn't leave to go to college. I quit out to reload... but unfortunately my last save was during the wedding. So I am still trapped. I have spent a lot of time on this family, I don't want to lose them. Please help!
