there is a quest called "Savage Severance" where you have to use Dr. Yzeth's security code in order yo access the rendering machine. The issue is that I can access the machine and it didn't trigger the response to complete the quest. This is my first time doing the event so it shouldn't be doing that. Either the quest is broken or I'm doing something wrong.

addendum: I completed both maps and went to the rendering machine. It still has a grey question mark.
