Like the title says I bought "Optimized for Roll20" maps on DMSguild but cannot find how to add any of these maps to my existing game. I am a Plus member with about 2.8 GB Free space left. I have eight games set up but only two are active. The content was a map pack, I can create a new game with the content enabled. The game I want to add it to was started from a DND module I own on Roll20. Any advice would be helpful.
