The season modules are not meant to all be loaded into a single game. It is possible that you overwrote something. You might be able to fix it by removing them and installing just the season you intend to run. A dev will probably have better instructions, though. From the Module's Marketplace page: Special Instructions Waterdeep: Dragon Heist is a different sort of module than those that have been released before on the Roll20 platform. Please read this completely before beginning your game setup (these instructions are also available in-game as a handout). In Waterdeep: Dragon Heist, the GM decides who the villain is of the story. In order to best facilitate running the game on Roll20, we have broken the source material up into one Module and 4 Addons, one for each villain/season. The core module contains all the information needed to run the beginning of the game up through Chapter 4, where the story truly splits. If the GM would like to prepare for the game by reading through all of the content, we recommend creating a separate game and adding in all 4 parts in order to get the whole story, deleting out pages (maps) if there is a performance decrease. When it comes time to play with the party, we strongly recommend the GM only add in the ONE relevant season to the main module. Adding others will create duplicate maps and handouts, and overwrite NPC's and creatures. To summarize: Create a separate game to view all the seasons at once, if desired. In a separate game with the players: Pick which season/villain is appropriate for the game storyline, and add only this addon to the core game. Track party progress on the [GM Page] Campaign Tracker if desired. Enjoy! If at any time the storyline organically switches to another main villain, we recommend removing the first addon, then adding in the second. Adding in another game will overwrite any shared NPC's or Creatures, so always create a backup before doing so just in case.
