I'm not sure if this was addressed already, but there seems to be a glitch in Iron banner where the rift spark is unable to be retrieved. My team mates tried to pick it up but the blue ring just kept going around and around until like a minute later, you can finally pick it up again. Forward to 9:33 in the video to view the glitch. I assume it is a similar issue to when heavy ammo glitches out and disappears completely leaving the other team to the advantage.

This glitch and the one where you can't seem to kill a lagging spark runner... yet he or she dunks it and then dies with a huge point gain, what the f**k Bungie!
