No clue yet how this quest log system works yet, but it's possible to remove the buggy Nova Steel entry by console command:
Place my
ConsolesOn.rpy file into the game's
game folder.
Run the game, load the last save and press
shift+o to open the console. Enter or better copy (ctrl+c) & paste (ctrl+v) following line:
Code:
quest_log.complete_task(questGeneric[18])
Esc-key to return to the game.
For the patient ones: wait for the next update where it hopefully gets fixed although using the command above shouldn't cause any trouble either as long as the quest has been really done by capturing her before.
The command to make the quest appear again if someone wants this for whatever reason:
Code:
quest_log.add_task(questGeneric[18])
This alone won't trigger the actual quest event to capture her though, so this is only cosmetic for the quest log.
