I just got a pro sub for a game on Friday, and wanted to add a few free token sets to my game, to get to grips with how Roll20 works. But when I click on the large "Free Token Set" button, it prompts me to start a new game. ... Which I don't want to do, I want to use that set in an already existing game, with a few other sets of the artist. (Devin Night) Those sets also don't show up in the "Your Purchases" section. What exactly am I missing?
