EDIT 2: As of update 2.9.1, this issue has been fixed! Original Post: I have the quest on my warlock and couldn't find the "Dynamo.Approach.Arch" node even though the quest was active. I noticed that ALL of the nodes were missing on my Warlock so I switched to my Hunter. While completing the 3 patrols and lost sector steps, there were nodes in the game world. As soon as I got to the "Node Accessed" step and crafted an override frequency, all of the nodes disappeared and the "Dynamo.Approach.Arch" node was still missing. Any help or info would be much appreciated. EDIT: I wanted to add that this also makes the sleeper stimulant quest broken because you need to access 15 nodes. I mainly play on PC so I also checked on my PS4 to see if the nodes were still missing, and they were.
