When I first played through the Fortress of Dawn mission my game crashed before the cutscene after the final trial and when I restarted it the game continued on to the next cutscene post-mission, the achievement for the mission would not unlock. I have now completed the same mission again on a new playthrough and the achievement still will not unlock
Same problem with me, first time ever doing the mission my game crashed right before the end and when I loaded it back up it said I already completed the mission.
I did not get "The Fortress Of Dawn" Achievement 30G .
I just now did the same exact mission with a buddy who was lower leveled, on the same javelin, and still did not receive the achievement. Frustrating I want my gamer score, this was also on Xbox One also.
This is really frustrating. I don't want to put in the time for another playthrough! I see the quest completed in my logs. I hope they fix this!!
