Since yesterday, I've been getting Bird errors regularly. I don't know if it's a true pattern or not but I've only gotten them while on Hunter Prismatic. Had it happen twice during VoG yesterday, then in a strike today, and was on final encounter of this week's nightfall when it happened again to me. Of course it removes reputation rank gains from vanguard playlist every time too which sucks even though it's not me leaving intentionally. Bah.
