Haven't noticed this, myself, but I haven't actually looked at my wish list in a while. You'll want to file an in-game bug report by entering (for example) /bug wishlist in the chat window. Fill in the requested info acordingly. 
Where to find me after the end:
The Secret World - Arcadia - Shinzo
Rift - Faeblight - Bloodspeaker
LotRO - Gladden - Aranelion
STO - Holodeck - @Captain_Thiraas
Obviously, I don't care about NCSoft's forum rules, now.
It's been gone since at least the 14th actually. http://boards.cityofheroes.com/showthread.php?t=280205

I listed a bunch of things in my wish list on the paragon market but whenever I view my wish list it appears empty now. I used to be able to see it but recently I cant and I don't know why. The items i marked on my wishlist still show the "remove from wishlist" button but clicking it does nothing and no changes appear on my wish list page.
Has anyone else experienced this and/or have a suggestion to fix it on my end? Or is this something the devs have to fix?
