Hi Waargrin! You are running into the difference between a module (only start new games with) and addon (add to any game). Dragonheist is such a huge module to begin with that they split the four alternate paths into separate addons. Roll20 does this to protect users from doing exactly what you are trying to do: combining assets into a game that will develop problems due to size. Very large games run into problems with performance, and can be very difficult to roll back, copy or recover. One thing you can do with that module is add one or more of the addons to an existing game. That will get you about half a dozen maps. Or you can create a Waterdeep game, go to the map layer and download the map image, then reupload it into your new game. You'd have to size and light it, so this solution is not ideal. Or finally, you can upgrade to Pro (even for just one month) for access to the Transmogrifier tool, which allows you to move just about anything between games.
