Hey so I'm 5 out of 6 for this triumph and just went flawless on meltdown. Something I've never done before, however the triumph didn't update to 6/6 and complete itself. I checked trials report to see on which maps I went flawless just to make sure. Turns out I did on: Altar of flame, dead cliffs, endless vale, burnout and anomaly. The triumph should be completed by now. Is this a known bug? Thank you
