Hi, I’m on mercury trying to complete the “bug in the system (heroic)” adventure but it’s telling me not all fire team members have unlocked this milestone. I tried looking around the internet and everything but can’t seem to find the fix. Please help... Edit: Thanks for the help everyone. For those with the same issue, you have to talk to brother vance in mercury and he will send you on 3 normal adventure missions one after the next. After this, you will unlock the heroic versions.
