Incapacitating Dahl Quest

Towards the end of the game, you can incapacitate Dahl instead of outright killing him. This opens up an option to leave the station, as well as allow for any crew members you've saved to leave.
I'm a little confused on the events here. I went with the following ending, so keep this in mind:
use the advanced Nullwave to destroy the Typhon
The quest for incapacitating Dahl sticks around for most of the endgame stuff, and for me it was sitting on "wait for Dahl's signal to leave" or something like that. However, at no time during the ending sequences did the quest update for me to leave that way. I noticed during the ending cutscene that a shuttle did leave Talos 1, but the quest just stuck around in that waiting state until the very end. Did I miss some other queues, or based on the ending I chose, is this intentional?
Best Answer
based on the ending I chose, is this intentional?
Correct. If you chose the other ending, then Dahl contacts you immediately after pressing the button. You then have a timer to get to the shuttle.
Massive spoilers:
Because using the Nullwave resolves everything immediately, there is no need for the simulation to continue. But after setting the self-destruct you still have the choice of whether and how to escape, and Alex wants to see what you do.

How do you complete incapacitate Dahl?
You'll have to crawl in by using the window by the stairs or the maintenance access panel. Either way, enter the room very carefully. Dahl himself should be in the room, so make sure you're stealthy enough that he doesn't notice you. When you can, use your Disruptor Stun Gun on Dahl in order to incapacitate him.How do you restore oxygen in cargo bay?
Look on the right side of the room for a series of oxygen filtration devices to find a broken one on the ground. You can repair it using 2 spare parts - or if you found an intact one elsewhere on Talos 1, you can place it in to restore oxygen to your friends.Where is Neuromod insertion room?
The Neuromod Insertion Room is on the second floor of the Neuromod Division. You may have been up here before to explore the Volunteer Quarters and the Simulation Debriefing Room.
