So basically what happened is this particular shop, the epicon, was listed as 'open' in the database (which shops like clothing rack etc are) instead of 'closed' (like special shops are). This was a mistake on my part when I went through and added all the shops to the special shops page. I've fixed this, though, so you shouldn't have it pop up from drills again. :) This was also why Mystery Box tried to use it today.
