Well I've finished getting 1000 points in killing bosses in Prison of Elders. I went back to Varik's and interacted with him. You can tell that he is about to give a selection on what gun to chose because the background gets fuzzy, but the problem is that there is no banner on the bottom that shows up for me to make a selection. Basically its invisible or unavailable. The only thing I can do is hit the cancel button and then it will take me back to his store inventory. I tried it several times to interact with him, but there are no selections to the guns just a Varik's looking at me stupid waiting for me to hit the Cancel button. And the bounty says to turn it to him. HELP BUNGIE!
