Repoduction 100%. Get the shroud equipped on 2 decks that the chest is different on both decks, do a deck swap and everyone else in the zone will lag out, or maybes its nearby you. And if you have done this they see the aura grow bigger but you don't. I believe it is causing errors and just super lags out everyone else. Once you have done this, you need to zone to fix it, even if you changes your cape, you will still have left over aura to others and still lag them on deck swap.
