I have noticed that the count for the armory and wpe vary. the armory has 473 unique and wpe has 474. Since the info comes from syncing with the armory and I would rather not go pet by pet are there any known pets that will show up on wpe but not on the armory site?
Here my Darkmoon Balloon was left off. Not sure if the same is happening to you, but when I first updated to the new system it let me add it manually. Perhaps armory doesn't see it either for some strange reason... Poor Balloon.
Yes I checked and do not see the darkmoon balloon on the armory as collected but I also do not see it in the list of not collected on the armory site. Do you see it on your armory page as collected or not collected?
