So, last night I and a friend stumbled across quite an interesting hiccup in the game.
We were in Sanctuary, and he decided to redeem his golden key. When he did so, the usual thing happened: he grabbed his loot, and for whatever reason, tried to open the chest again. Much to both our surprise, the chest reopened, granting us more purple class items. Of course, we tried it again. Surprisingly, we got the same result.
45 minutes later, fatigued from grinding the black heck out of that chest, we decided we had broken the game enough and moved on.
We have no idea how we caused this to happen, but I've seen posts on other forums detailing similar incidents. Has anyone here had this happen?
