Since the recent patch, I am now unable to enter Odin's Chamber II, though I meet the requirements to enter, and have killed Arch Odin many times. Now when my linkshell enters the battle I do not meet the requirements.

Despite having Mark of the Einherjar, having POPPED and killed the first Odin, and have killed the second Odin. I bought all 9 feathers to see if that could be the issue, no change.
