I've noticed that sometimes Wishlist 2 and 3 does not load when i try to edit my trade. This happens rarely but it is very annoying since if you save the trade you lose the items you had on Wishlist 2 and 3 that were not loaded. Wishlist 1 always loads.

I am not sure if this is a specific browser issue, i'm using Mozilla firefox.

I've had the same problem sometimes, the wishlists don't load. If I don't notice they're gone, then they disappear permanently when I save. I've been noticing this bug for about a week.

Actually, sometimes wishlist 1 is also not loading, but if you try to save then, you just get an error message that all the wishlists are empty, so then you can reload the page to fix it.
