Some of the games you create do not or no longer have cover art after being created and require uploading a whole new art asset. I have test this with several modules (both free and paid for). I have also linked the test game in question. List of games that do NOT work (some used to before) Tomb of Annihilation ( game link ) [Dungeons & Dragons 5th Edition] Waterdeep: Dungeon of the Mad Mage - Adventure Preview ( game link ) [Dungeons & Dragons 5th Edition] Xanathar's Guide to Everything (Underworld Speculation; game link ) [Dungeons & Dragons 5th Edition] Against the Aeon Throne - AP1: The Reach of Empire ( game link ) [Starfinder] The Lightless Beacon - Call of Cthulhu ( game link ) [Call of Cthulhu 7th Edition] Quick-Start Rules Call of Cthulhu ( game link ) [Call of Cthulhu 7th Edition] Adventure Preview - Explorer's Guide to Wildemount ( game link ) [Dungeons & Dragons 5th Edition] Torment and Legacy Demo Adventure ( game link ) [Pathfinder 2nd Edition] Pathfinder Society #1-15: The Blooming Catastrophe ( game link ) [Pathfinder 2nd Edition] Starfinder Society Quest: Into the Unknown ( game link ) [Starfinder] Devil at the Dreaming Palace (Agents of Edgewatch AP 1; game link ) [Pathfinder 2nd Edition] List of games that DO work indicating that the above is not working as intended: Pathfinder One-Shot #1: Sundered Waves ( game link ) [Pathfinder 2nd Edition] Starfinder One-Shot #1: Band on the Run game ( game link ) [Starfinder] Pathfinder One-Shot #2: Dinner at Lionlodge ( game link ) [Pathfinder 2nd Edition] Head-Shot the Rot ( game link ) [Pathfinder 2nd Edition] The Great Grav-Train Robbery ( game link ) [Starfinder] Vampire the Masquerade - Auld Sanguine ( game link ) [Vampire the Masquerade 5th Edition] A lot of this could be temporarily mitigated (though not resolved) if game creators could manage their art assets outside of the game (as per my suggestion; here ), but again that is really just a temporary fix. None of this is really game breaking per se like a lot of the serious issues this platform currently has above and below, but I will say that it does affect presentations of the game as well as the convenience of this platform; especially if one has paid for the product and the service.
