I have tried literally all these aforementioned bug fixes for when I can't get Galmar to give me the Reporting In dialogue option. Playing on PC, I've even tried the PS3/360 suggestions just in case something could've worked. In my situation, I'm at the Battle For Solitude part of the quest. Is there a console command I can do, or something else that might let me see the Reporting In option at all that others have managed to get to work for them? If not, is there something I can fix or force so that I can get the option?
EDIT: Sorry if there's been many more posts like this, but again none of these solutions have helped me unfortunately. I haven't started Season Unending yet either, which I'm afraid will make the main quest bug out at that point as well, or so I've read from other posters.
