I just encountered a bug where my Sim's wedding (with My Wedding Stories) can't end. There isn't an X button to end it like normal (pictured below) and the wedding event no longer appears on the calendar.
The only solution I've found is to exit to the main menu, click "load game" so you enter the save via Manage Worlds rather than live mode, and then visiting a different lot with all of my household's Sims.
I have most DLC installed except a bunch of kits, Life & Death, Enchanted by Nature, and Adventure Awaits. I also play with script mods (including a few UI mods) and custom content installed, so I'm not sure if this is a mod bug or a game bug. That said, none of the script mods I'm using are new to me and I've never encountered this before with them installed.
Yes, same problem here.
Couldn't use M, go home, or an X and even saving and going to main menu didn't solve it.
But! My freshly wed family could go volunteer together through their phone menu.
After they did, the social event finished 🥳
Just needed a bit of a good deed to get out of wedding prison 🤔
