Hello All,

I have come across a "bug" with getting the Legendary Dragon achievement on PS3
Background, I am level 81 and have been since the first DLC Dragonborn, then Hearthfire , both DLC’s are completed. Then I downloaded Dawngard. The moment I came out of my breeze home a dragon showed up, it just flew away. I continued to finish the DG DLC, now; I look for a legendary dragon. I have been to every dragon post a few times a day since last week Thursday. I also been to College of winterhold , Dawnstar , and other known areas , where this dragon should appear.
There is a dragon appearing every single time I travel, I just have to wait 30 seconds and a dragon shows up. The dragon has no red marker to attack. I have tried arrows, incinerate, the moment I cast a flame atranoch it just disappears. I use dragonrend constantly, my screen flickers and the dragon turns blue and keeps flying around. I usually get lucky in the dragon spots and I can use bendwill to ride another dragon and catch the dragon with no name , when I target it , and hit it , it disappears , literally , just goes away.
My question
1) is that the Legendary dragon?
2) how can I attack it ?
3) anyone else with this issue?

I have a save file from level 71 – 81 each level so I CAN go back to before the DLC’s if necessary.
I loaded my level 78 file last night; same issue just flies around and “roars” no red marker, nothing.

Help!!!
