I have this exact problem as well. I can continue doing the extra work missions for the Thieves Guild, but the main questline appears to be broken for me after completing Loud and Clear. There is no log entry to speak to Maven now, and she only has the normal dialogue options when I find her at her home.
How did you handle the horse stealing quest (Promises to Keep) and interaction with Maven? I wound up talking to her about it and telling her who hired me to steal her horse. I was able to complete that quest just fine, but I'm wondering if that may have broken something in this main questline that caused Dampened Spirits to not begin correctly. I also wound up killing all of the Black Briar mercs up at the lodge, so that might have had something to do with it. Those are the only things I can think of at the moment.
I just stole the horse and gave it to yourman...the mission giver.
Never spoke to meaven about that quest
I luckily didn't encounter this bug but I read on one website that it occurs if you interrupt dialogue with Brynjolf too fast.They said you must wait for him to finish the conversation.
I've went back over the conversation a lot of times and let the conversation run its natural course and its natural pace
I'm having the same issue as well. I recall being paid, i think, but have no follow up quest.
If it means anything, I've done the rebellion quests on the side of the empire. After some reliable google searching, I find out she comes to replace the Jarl that was previously there. Does this perhaps super-cede her position in the thieves guild making the quest null? :/
Forgot to add that upon talking to here, there are no dialogue options.
Yeah i know mate, apparently there is some bug if you've broken into one meadry's before you'r giving the mission it causes this bug...bit of a joke because as a natural thief i like to break into places...
Also the console code doesn't work, just get a spam feedback reading as follows:
"getinfaction >>>>>0.00"
or something very much like that
