I was doing "the corrupt" strike when I saw an exotic engram dropped. It turned out to be a huckleberry, which was a weapon I didn't have. But now, after the non needed rollback, it has disappeared. I don't see how losing materials is a big problem, as you can buy loads from Spider, and silver... Well... Just get a job and buy some more, or show bungie a receipt. My point is that getting materials is not hard and the rollback was not needed. I am upset with this patch and would like my huckleberry back.
