I have a bug whenever you first see Maramal he's in the Bee and Barb and has some sort of scripted scene, but I'm having a bug where he doesn't start the scene and won't leave the Bee and Bard, he just stands there on the rug he would normally start on, anybody know how to fix it?

Takes abit of exiting and entering but you'll get it to start.

I've been trying all of that, do you think there may be some way to use the console command to get the scene to start? Even after I get married he still returns to bee and the barb and still wont stat the scene

Well if you're married then who cares? He isn't really needed for anything else apart from getting married.
