*LATE GAME SPOILER* Main Quest Bug at "Hand Over the Calcaduceus"

[bbrr18]

Hi, I've played through The Archive, repaired the AI,  cleared the whole area, reclaimed Spireton, and processed the Rift Data. Right after processing the Rift Data I get this objective to "Hand Over the Calcaduceus" right outside the AI's Room. But there is no NPC there.

I'm confident I've done every single objective leading up to Processing The Rift Data:
1. I checked my quest journal and apparently I still need to repair The Archive despite already doing so. (Cleared Underlands, Punching Cards, and Reactor)
2. Reclaimed Spireton through stealth without the Order's help. But this was after I've cleared the Archive of protectorates. The leader NPC in Spireton doesnt trigger any conversation to get them going into the Archive.
3. I can still proceed with the Main Quest. Got the conversation trigger from VAL about Horizon Point reappearing.
4. However I am proceed to get Auntie's Choice and The Order to ally with me for this final quest due to being unable to proceed past ""Hand Over the Calcaduceus" objective (I opted and succeded in forming the alliance prior to this. I've helped Auntie get a body too)

Supporting screenshots attached.

To add on a few notes:
1. No mods installed
2. Did a clean reinstall just in case, to no avail
3. Used cheat engine to make me move faster. So I can move around fast to check if I missed anything. Bug happened to me before cheat engine was used.

i'm having the exact same problem. this game's quests are buggy as hell. this is the third quest (fourth if you count a completed mention that won't disappear) that's impossible to finish due to bugged out npcs. the other two being that moon man guy in the brig, and i can't turn in the quest for the lightning towers because the quest giver has vanished. i've been loving the game so far, but what the hell?

You have to cross the bridge and flip the switch to allow the order forces to come down on the elevator.

This has pretty much ruined the entire game for me. I just did so much to get the order and aunties choice to cooperate. I just went through all the stuff to get Archive up and running, just to get to the end and have it be bugged? CRAZY! PLEASE FIX! im probably not going to play until theres and update fix, if theres an update fix.
