I created a large campaign from scratch that took my players from level 4 to 10. Our game includes a ton of maps, images, and sheets. To take the next step (and since I don't have as much time), I purchased Tales from the Yawning Portal. This was partially because it was advertised as "All Access Vault Enabled." When I tried to import characters exported from our custom campaign/game into the game with the Tales Addon, I was unable to do it at all (says its a limited use vault game). I've reached out to tech support, but wanted to know: Are there potential problems with adding on a Tale from the Yawning Portal right into our current game? Are there concerns about file sizes or number of characters/sheets/images in a single game? If I absolutely have to (and it doesn't break stuff), I can simply add in one of the addons into our existing game. Ideally we can import into a fresh game, but I appreciate your thoughts on possible problems with adding an add-on to a homemade campaign/game. Thanks! Matt
