Can't start "Royal Ascent" quest.

[Skeleton Knight]

The end game quest to host High Stellarch doesn't work.
The button is always grayed out (with the met requirements) and even "Dev: Accept Instantly" doesn't start it.
Anyone faced similar problem?

I know my info is vague. If you need any other info, I will provide.

The bedroom you have for the Stellarch has to be vacant to accept the quest. I had the same issue and had to vacate the bedroom for a few hours and it allowed me to accept it.

Might not be the fix for you but thought I'd share.

you are not using any mod like runtime GC that can screw quest over, are you?

I do have a long mod list but not anything that touches quest system.

it wont hurt if you share it here. Just because a mod doesn't say they dont touch something, doesnt mean they are not touch something.

So I went through your mod list. There is too many so I can't say for sure, but these are the mods that may cause problem in descending order:

1/Dynamic Diplomacy (tampering with background pawns, the high Stellarch most likely killed in one of the conquest battles)
2/More Quests (change quest system)
3/Royalty Tweaks (possibly broke the save file by referencing old dlc stuffs)
4/[KV] In-Game Definition Editor - 1.1 (gut feeling)

Even if you remove the culprit mod, I don't think you can fix your quest. Your save file is most likely broken beyond repair.
