I purchased the $30 tier of the current Humblebundle with Roll20 modules, and they are listed in my Compendium, but when I try to create a game they are still listed as "purchasable" in the Modules section. I can't use them in any games, but I can read the books in my Compendium. How do I get Roll20 to recognize that I own the modules and let me use them in a game?
