There's a marriage bug. I can start the process of marrying a second character, deliver all the resources, but then when I go to the church all it does is let me start the process again, without actually doing the marriage.

I did update the marriage quest in the last release. You need to complete the workers and servants quests for each marriage now. I just successfully married Ana and Amelia. I also verified that the version I uploaded is the version I'm playing with. Did you check your Journal to see what the quests say? Are you playing with any other mods that may affect the marriage quest? FYI it's easier to trouble shoot mod problems on the discord channel. I check that almost every day.
