Stuff missing from the store

I was making a game in Roll20 when I noticed something that looked interesting in the From the Marketplace section.  I clicked on it and got a 404 error.  I clicked on several other things and either got a blank page or another 404 error.  I searched for some of the items in the marketplace and nothing came up either by title or publisher.  I searched for some of the publishers through Google and found their publisher page but there's no product at all listed.  Some examples are Cruor Games and Castle Skydawn Design.    

Hi Michael! Can you identify the product that was listed in Roll20? I'd like to try to duplicate the behavior. You can also just report this in a  Help Center Request  if you prefer. That would be more direct than a forum post.

It's not a product.  It's pretty much all of them.

I just mean the name of something that I can see while in-game that I can test against in the web interface.

Stage Fright at the Playhouse

You might need to contact the team directly. ( Help Center Request ) I am seeing  Stage Fright at the Playhouse on DriveThru RPG as a Roll20 module, but the author does not seem to be cross-selling in the Roll20 Marketplace. I can't seem to get a reference to it to show up in the in-game "From the Marketplace" tab (which should only be art packs in any case—this seems to be an adventure module). Sorry I'm not able to help any better, but I can't replicate your experience. (I can't find the link that is leading you to a 404 with the information given)
