I was visiting my gallery ('Up For Trade') to take an item out, and I got an achievement announcement for Making A Living. I was a little confused since this is a gallery that has Never sold anything.(obviously) I visited my Achievements page and it said

Making a living Have a shop that has made a total of more than 1,000,000sP! 52,066,614 / 75,000,000

Now, I don't remember exactly where I was at on this achievement before, but I only have ONE shop and it has only made 20-something mil Tops.
Did I somehow earn this from a previously retired shop (that I still have but can't use)? And it seems like such a random amount...

Anyone else have this issue..?

are you including totals from shops you had before the shop overhaul?
