I will just add on here that I recently played a wedding again with My Wedding Stories. It mostly isn't buggy for me except that the first dance can still be glitchy and yet a second time, someone flirted with the groom while I was setting up the first dance. I was playing both the bride and groom and it happened again so I think there is still some bug for the first dance. It takes too long for them to start dancing and I ended up using the slow dance.
Other than that, everything worked and I understood what I needed to add to my pre-existing venue for it to function for those types of weddings. While sims can still just elope, I do think they could have kept the original basic weddings as well. I will say that for some of my main households or favorite sims, the weddings are upgraded and everything other than the first dance worked nicely. I will continue to use the pack to make some weddings in my rotation more elaborate and to involve more of my sims such as family and friends in these events.
Tartosa remains a great world for romantic trips or for some lucky sims to live in. Basically there's a learning curve when you first start using this pack but it's mostly working well now and if you do want to customize weddings then it lets you do that. I'll keep using it and I am glad that they added it because romance options were more limited before. We could honestly have more than we do.
