For some reason when checking on my shops page, I just managed to get the last tier for the Making A Living achievement (1,000,000,000sP mark). The problem is, I don't have a shop that did what the listed requirement is.. (Have a shop that has made a total of more than 1,000,000sP!). I had the previous tiers already but they were from my old deleted legacy shops, my new shop isn't even a quarter of the way there. Does the achievement actually apply to my entire shop profit history, or could it be a glitch?

Ohh okay, thank you, I didn't know that from the achievement description.
