There was a weird item on my wishlist, so I clicked on what I thought was the "Unwatch" button.
Then I realized i'd put it ON my watch list instead.
So I took it off again and now it is the ONLY item on my wishlist.

I tried adding some of my wishlist back, but it is acting REALLY weird.

Is this a known issue right now?

Mine seems to have started in that position... with an item I don't think I've ever wishlisted. It too wasn't on my wishlist yet.
I can't get it off mine how did you?

Hmm indeed. My wishlist will only show the item I just put in it. I'm gonna quote our posts over in the Server Update thread and ping yanyan to it so he and Inso know we are having a Wishlist issue

Right now things seem to have gotten fixed to the point you can put one item on the wishlist at a time. Putting a second removes the last one you put on. And of course refer to the server update thread as Yanyan and Inso keep working on these issues. ^-^
