As I quest I've been stymied several times by items I try to buy through Shop Search that direct me to an error page saying "this item is part of a gallery! you can't buy it" (approx.) All of these items present as actual buyable items, however, with prices and a 'buy' button. I've never seen this before - is it a bug?

I've noticed this several times too, it's a little odd. The prices show up on Shop Search, but once you go into the actual gallery everything is listed as "display only".

The only thing I can figure is that these users switched their shops to galleries suddenly and that change isn't fully reflected in the system yet. Which is still really weird, considering this usually isn't a problem... :0

It must be a recent change though?? I haven't come on much in the past few months but i've been on the site 8 years and I've NEVER seen gallery items accidentally pop up as buyables...that's the point of the separate search, after all.
