Dragon Heist - adding all modules

I'm planning on running my current Dragon Heist game along the lines of The Alexandrian Remix ( <a href="https://thealexandrian.net/wordpress/41217/roleplaying-games/dragon-heist-remix-part-1-the-villains" rel="nofollow">https://thealexandrian.net/wordpress/41217/roleplaying-games/dragon-heist-remix-part-1-the-villains</a> ). This involves having all the villians active, and the players having to raid most of the lairs. It would be great if I could import all of the seasonal modules so that I can use the premade maps and tokens and so on, but in the product description we are warned against doing this. Does anyone know what are the things that break if you add multiple modules? Are the things that break fixable?

Please tell me if I'm posting in the wrong forum.

I am not familiar with the idea, and I do not own the module. I recall from discussions about this at the time of the module's release that some elements were duplicated (yet different in details) in the various seasonal add-ons and would overwrite each other if you loaded another add-on into a game. If you already own the module here on Roll20, you can try loading them all into a test game to see what happens. If you do not already own it, perhaps someone here who does will offer to make a game and invite you to it to see how it looks and runs with everything loaded. If you own the adventure in another format outside of Roll20, you can manually enter the relevant portions of information based on the essay you linked, but that could take a lot of time. An easier, but more expensive, option would be to buy the module here on Roll20, and up your subscription to Pro for a period of time. With the module you could create four separate games, one for each season. Then create a fifth game (the game you intend to run), and use the Transmogrifier (a Pro subscription feature) to move maps, handouts, and character sheets from the four separate games into your remix game as you need them. This way you could be sure they would not overwrite.
