Ok so yesterday I was playing throung the Shadow Thief strike with random matchmade people. You all know that in that strike, you fight Taniks twice before the last room, each time dwindling his health down so you can kill him in the final room. Well somehow, we managed to annihilate the Shadow Thief in the second room! When we did, the level didn't end, though. It told us to continue. But the door to the next room was locked! We had to quit and restart the mission to finally beat it. Surely we aren't the first to do this, so comment if you've done it too and let's see if we can convince Bungie to patch it so that it will end the level when you kill him, and maybe even get a bonus reward for it ;)
