Not sure if this is a widespread bug or something wrong with my install? One day I would be able to search for a specific item in the player shop even by only partially typing out the name, the next I wouldn't be able to see it at all in the shop even if I type the name out exactly. Confirmed with multiple other people in the game that items I am searching for are being sold.

Any known fixes?

People seem to think it is a missing file on the user end. I haven't had an issue personally, though. All I have to do is partially put in a name and hit search next to the text box and then select the specific item I am looking for. After that, I have it list the item by price. If no one is selling it, it doesn't appear in the search list, whether people have bought them all since the last search or none were up to begin with.
