Since firing up Skyrim with all the official DLC's, I started out again as a fresh new character. However, it seems I've run into a glitch with Maramal and the wedding ceremony at the Temple of Mara.
Everything works perfectly up until the ceremony. There Maramal asks my spouse-to-be the question and they answer with 'I do, now and forever'.
At that point Maramal simply stops and control of my character returns to me. He doesn't proceed to the stage of asking me the question, nor do I get the 'I do/Stop the wedding' dialogue options. Clicking on Maramal states 'This person is busy' and my spouse-to-be has a standard 'happy to get married' line.
I've tried everything I could think of, but nothing allows me to proceed beyond that point and attempts at forcing it with SetStage 100 still fails the quest upon leaving the temple. Even with all the Unofficial Patches enabled this glitch seems to persist.

I've done some extensive reading on the internet and it seems several people experienced exactly the same issue. Some believe this behaviour started after patch 1.7 was released.
So I was wondering if someone could check up on the script-sequence for me and see if there is an issue with them? The exact point of the issue should be right after the spouse-to-be states 'I do, now and forever'.
Something tells me that it may have something to do with the patch 1.7 (issues with actors?) and/or the Hearthfire DLC (because of the ability to move to the new homes), but as I'm not overly familiar with scripting I can't verify this. Another thing I noticed is that certain NPC's like the Courier don't 'force-dialogue' either after a while. Usually they came running in and opened up dialogue automatically, but now I have to manually click on them in order for them to start. Maybe this behaviour is related?
If anyone can make (or point me to) a (Hearthfire compatible) mod that may fix this glitch with the wedding ceremony, or a workaround, I'd really appreciate it.

Greetz,
