I got a gold key from the weekly so of course I wanted to use it and what happened is after awhile I reached a wave of zombies and most of them were killed by my Photon Blast (Julius Nifta) but about three or four of them survived and I couldn't kill any of them. Thinking that it was lag I just waited around and then a few minutes passed and nothing happened, I was taking one damage every so often from their attacks but most did nothing, and I even fed my mag just fine as well so the quest bugged out and I was forced to close the game losing my gold bonus key. Here is a screenshot of what it looked like.pso20200819_004831_000.jpg
