Hey there, this is a problem that has occurred in the past for the same roll20 game, it's a rather large (player & sheet wise) West Marches game which we have previously thought was the cause but the last time it "sorted itself out" after a few months. This is the game in question: <a href="https://app.roll20.net/campaigns/details/4356021/taming-carracosta-the-second-expedition" rel="nofollow">https://app.roll20.net/campaigns/details/4356021/taming-carracosta-the-second-expedition</a> As for the exact problem: The owner of the game makes a copy as you do normally. The copy gets made, but it ends up looking like this (completely empty): As opposed to the original game: Last time there was back and forth with support, and the answer the (Pro) owner got was "It works fine on our end". But it obviously did not work for us. And then we deleted roughly half of our maps and cleaned out lower CR sheets, it still didn't work. A week or so later, another DM from the game posted a thread here, and after a while it seemed to be working again. But yes, any help would be appreciated, as not being able to make a copy of a game that large is a bit of an issue, and since it is a West Marches, being able to run sessions at the same time on two different copies is quite handy.
