I was in a group trying to make room to obtain the items in the chest after final secret puzzle. I was able to grab everything except for the emblem when the leader of the fireteam click on cut scene and started it. We were teleported out into the cut scene. When we returned I was no longer able to open the chest and get the emblem. I tried on all my other characters and even did the puzzle on my own. With no luck. Is there any way to get?
