So, this error is nothing new, but the frequency of it has changed since the server move debacle. For the first wave of Steamworks Menagerie items, I didn't encounter this error at all. I was able to buy an item, instantly move it to a collection or my wardrobe, then go back and buy another item. Rinse and repeat.

Since the server move, I get this error every.single.time I try to buy something. It's inefficient, obnoxious, and something that shouldn't be happening with this frequency.

I'm having the same issue and unable to purchase anything.
