After Bungie changed the grandmaster to a strike I don't actually mind, I farmed the grandmaster a couple of times this week, making a post to do so since for some reason no one accepted my application. Getting through it without dying each time, I did notice some weird lag going on. For instance, in one grandmaster you would see the player up ahead stuck and standing against the doorway as the strike was being entered. Enemies as well appeared glitchy sometimes.
