Cannot start The World-Eater's Eyrie

[Georgeman9000]

The Fallen is shown completed, but it won't start the next quest.

Balgruuf is glitched, and keeps initiating conversation with me, but does not offer any new dialogue options.

No guard exists that I can talk to to free him.

And no, reloading a new save is not an option because I finished entire Dawnguard in between. And the last save I have before that is literally 50 hours ago (and yes I use autosave manager)

Console command "setstage MQ303 10" doesn't work because it wants me to "getinfaction"

I'm using quite a few mods, but I don't think anything that will interfere with mainquest.

Help?

Also I can't pull the chain myself either.

If it helps, i skipped paarthurnax quest thru setstage command.

As nobody could help me on this, I semi-fixed it through extensive consoling.

1) coc to skuldafn to go through the dungeon
2) player.additem the diamond claw
3) Nahkriin does no spawn, but he's not needed to enter Sovngaard because his staff is already set.
4) Enter Sovngaard. Setstage MQ304 10. (though I guess you could just skip the entire Skuldafn and coc straight to Sovngaard)
5) Play till end.

Other than Nahkriin not spawning (I assume I can use "enable" but haven't tried) and Odahviing flying with his head stuck in he snow at the very end for some reason, it got me to the end fine.
Though I don't think Call Dragon shout works anymore.

I googled and there were some similar cases like me, so hope this helps.

after 8 years, this is the best fixed :)

Recently, I had the exact same bug mentioned, I worked it out by using Georgeman9000's solution

But I really did want to check why this is happening
So I passed it all vanilla up to this point and made a save there
(Btw, you can pass until this point very easy if only you do the main quest and just use teleport 'coc')

Then loaded all the same mods I had that caused the issue and tested them in the vanilla save

Turns out that the broken script is in the save file itself because all the mods were applied to the vanilla save and did not cause any change in the fight

Loading my previous save with the same mods brought the glitch back

So, the broken scripts lie in the save file itself and even if you change the mods in the mod manager you wont't get a change in the game. The best solution is the above mentioned.

Now from what i got to understand,
it's probably from a bad SKSE installation, I personaly used to move all the exe and dll files of skse to the game dir but would move the scripts from the mod manager, that was not wrong unless you keep for the skse and all the base libs the highest possible priority

In my earliest logic i used to believe that the core libs should have a low priority to allow other mods use them, this was not right reasoning as even though these are a base for many mods they should not be able to be overwitten, as many mods tend to want to overide them as from what i've read ex. campfire overwrites some papyrus util scripts. Mods should use but not overwrite them as this causes other mods to glitch

so solution 1: install all skse (exe, dll, scripts) in your base dir without any mod manager
solution 2: if you install skse from mod man keep the highest priority possible

Install all the core libs with the highest priority possible

All supermods (mods that tweak a lot of stuff should go to the lowest possible priority espesialy if they are not frequently updated
