So after today's patch, all of my incomplete EOK Collections that I have collected but not completed sets was wiped. Such as 4 dusts collected, not any more. I was only missing 1 giant table leg on another set for Unearthing the sky. Now It shows all are missing. Even to the point of showing the actual items I have collected as not collected. This has also happened to several other of my guild mates. Thanks for another wonderful patch.
Some folks have mentioned this over in the update bugs forum, you may want to also post there so they see more than just the few already there.
