I'm level 50, power level 650, and I've had the Prime Attunement buff for a while now. Everything has worked correctly up to now and I've gotten Prime Engrams with powerful gear. But today, my Prime Attunement buff has gone away: it's no longer showing up on my character page, where it's normally displayed. I noticed its absence after using a Tincture of Queensfoil and only seeing the Ascendance buff on my character page, with no other buffs active (I haven't used a fireteam medallion in a while). I've tried logging out, restarting my system (PS4), to no avail. Anyone else had this issue or know what's going on?
