UPDATE: I fixed the bug. I typed out my steps as a comment below.
There are no Typhon in the surrounding area (definitely no Mimics as I scanned everything with my Psychoscope with the mimic scanning chip plugged in), and no remaining Typhon in the Cargo Bay.
A list of things I tried to do:
1. Reloading old saves
2. Restarting the game
3. Restarting Steam
4. Reloading to the part where I got the Fabrication plans and the power and did it in the other order.
5. Placing the turrets in different spots.
6. Hacking the door instead of using the code (after placing the turrets down)
7. Hacking the door instead of using the code (no turrets placed). It earned some disapproving comments but quest still does not update.
8. Exhausting all dialogue from Elazar, Ekaterina, and Igwe before placing the turrets down.
9. Exhausting all dialogue from Ekaterina after clearing the Typhon.
10. Killing everyone before hacking the door open.
11. Killing everyone after clearing the Typhon.
12. Folding up one of the turrets so that the fight lasted longer.
13. Folding up one of the turrets so 1 or 2 casualties were the result.
