I've completed the Infinity Plus One adventure on Mercury, and received the legendary reward from Brother Vance, but my milestone did not update. I have a milestone which still says, "Speak to Brother Vance in the Lighthouse," with a listed reward to Legendary Gear. When I speak to him, I see a list of Mercury Adventure tokens, which I am unable to do, since they say, "Already Completed." I'm assuming I shouldn't see a list of regular adventures, and that the screen should be similar to Ikora's meditations when I visit her. When I first talk to Brother Vance, I see the heroic adventure tokens, then have to hit escape to see the (I'm assuming bugged) regular adventure tokens and the option to turn in reputation tokens.
