Is My Wedding Stories playable after the patch?

Oh yeah, no, it was definitely broken before this patch. Actually I hesitate to call it broken because broken implies things were not working as intended. From what me and a few other people who understand xmls and game code discovered, it was plain straight not finished. Lines of code were half written. Interactions were missing big chunks of required scripting. None of the features were internally connected. I said verbatim on the survey they sent out to buyers, "this is like handing in an incomplete assignment to your computer science class teacher."

I really feel for the dev team, I wish they had gotten more time to actually finish the pack. I'm glad they finally patched it and everything is smooth for me but I also still hope other people can somehow get my luck with this too because a big thing we were discovering in several discord servers I am in was that for some bizarre reason, things will run perfectly sometimes and then just not work at all when you try again. Replicating certain things for us was genuinely a challenge and we were all aware of how broken things were, so I do actually believe the gurus now when they say "oh but it worked before." I personally think it's connected to the calendar function - somehow I think using the calendar doesn't have the event trigger properly and therefore it won't assign the sims involved the correct roles.
