Empty slot in coin shop#1127

I have been wondering why sometimes there is an item entirely missing from the coin shop, and I figured it out.
I decided to open the “ROA2 - unofficial companion” app on my phone to check the shop, and it showed the missing item (,or at least the name of it). The shop had picked an unreleased item for one of the slots (Pixel Gouie), and couldn’t show it.
Not a big problem, but there should probably be some kind of check or exception to make sure that doesn’t happen.
