I ran into some impassable bugged quests during my playthrough, most notably in the Companion quest line and the main quest line. So I explored the console commands to find a fix and put them up on youtube to help others. Someone suggested I post them here.

Comapnions. After the silver hand attack your companions are stuck in permanent mourning and you cannot continue the questline.

Season Unending. When you are told to arrange the peace conference you can talk to neither of the leaders if you have started their joining questlines.

I've found that most of the bugged quests can be solved hassle free using the console so if anyone has any other requests for bug fixes then I'd be happy to look into them.

Unfortunately I can'y post links but if you search on youtube for the above workarounds then you should find them.

Here's the links:

Thanks Jackstarr. Hope they help people.
