Items getting removed from wishlist (CLOSED) (CLOSED)

I noticed a couple of times now that items by Ion on my wishlist will get removed. It's only items by that vendor. I know he is the site owner so is that intentional? 

Yes, Ion is the owner of RenderHub. He uses his products (and sometimes mine) for live testing of features. 
He may be working on something that would cause the item to be temporarily unavailable. 

FYI - If *any* vendor disables their product for whatever reason, it would disappear from your wishlist, too.
