YES! We finally beat it last night, but should have beaten it long before that. Crota chased our sword bearer to the room on a few occasions, then magically teleported to the other side of the map. We had the same issues with the sword bearer that you did.
One time when we got Crota to enraged, he got up and swiped our invisible hunter in one motion. The glitches absolutely kill this raid.

Congratulations! On Crota, you fight the glitches.
