In Galactrix's UGC mission "Syndicate Extraction" (which is now on Holodeck - well done!), you run around Pax's station trying to find the Orion deep cover agent and while you're running around you can talk to various people on the station. They all have the yellow "Contact" icon hovering above their heads and an interact button "Talk to xxxxx" appears when you run near them. BUT it is not a mission objective to talk to any of them.
How do you do this?
I have added an NPC contact to one of my maps and typed a message into the contact's 'Default text' box, but when I test the mission she doesn't have the icon hovering above her and no interact appears to talk to her when I get close to her.
How can I do it without adding a "Talk to contact" mission objective?
