Just tested out the wedding after the list system was patched, but there seems to be a bug over where Amelia discusses the 'use of bride' with you. Refused to invite said people, but the event played at end of wedding anyway where they do.
Only tested this with princess as bride, so not sure if it affects other spouses or if this is only for Ana.
UPDATE : Tested with Daisy out of curiosity. Same issue.
And as a side note, I find it odd that she remains listed as 'slave' afterwards, even with wife class. Not sure about how it all works in game lore, so maybe that's how she'll always be. Just kinda figured she'd at least be counted as 'free' if she's your wife. Especially since you're the mayor :)
