Lost to the Ages Quest Bug

[Realistic]

So early on in my playthrough, I accidentally found an Aetherium Shard and didn't think anything of it other than "Hey i can sell this ig". I kept it until finding the Lost to the Ages quest, and while trying to reach the summit, i accidentally Fus Ro Dah'd Katria's ghost off a ledge, and when i got to the puzzle at the end of the caves, i completed it and retrieved the shard, the quest didn't update. Idk if it's because Katria's not there or what, but if someone knows how to fix it can you please help me? also i did the setobjectivecompleted command and it still hasn't updated the quest

You may have made things worse by resorting to a command console line. Do you have a save from before you used that command and before you blasted the ghost away?

This.
Load an earlier save.

Also, be sure you have the Unofficial Patch installed. This quest can be buggy without it.

Protip: Now that you know what the shards are, do not pick any of them up until the quest begins by first reading the book called 'The Aetherium Wars'. Once you rad the book, the quest begins and you may freely pick up any shards. There are many locations to find this book.

Actually, if you have all the shards you dont need Katria to reforge the crown (or whatever is on your whishlist). In one PT, Katria got stuck, I couldn't talk to her, still finished the quest and got the crown

So ig i figured it out cause i essentially loaded an earlier save that was only a little buggy, left the area, then when i went back in i just had to go around a corner inside the room with the shard and it worked so it's all good now. thank you for the advice tho :)
