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.
Ok! This was plaguing me for two days. Finally I went to the neighborhood my sims lived in. Clicked on their house and then clicked visit highlighting the both of them. It brought them home and they were still married! So the wedding still happened without having to do it all over again.
