I'll add an example of what I mean. Tonight I unlocked an appearance, and when I click on it in chat, it shows a random BFA chest instead of the actual chest that has been unlocked. You can see in the tooltip how the chest should look.

Often after closing the appearance window and re-opening it will show the correct pieces.

Notes: User appears to be taken to the correct page and appearance. The issue is that the displayed appearances are the ones found on page 1.

Tentatively marking as fixed. I think the issue was in the sorting functions. I have not seen the problem occur since I made the fixes, but it happened so randomly its hard to be completely sure of the fix.
