Okay, so, the most likely culprit is me, myself, and I, happily clicking away without double-checking things, but I can't seem to figure out what I did. I had 22 DS earlier today, and now I have 17 DS. I assumed I had purchased something, but I can't find anything worth 5 DS in my wardrobe or inventory that I don't remember being there earlier, unless I've missed something (or my brain is faulty; this is entirely possible). Is there a way for a staff member to see what I've done with it?
