You might want to submit a ticket through the Help Center with the info from the troubleshooting steps. <a href="https://wiki.roll20.net/Solving_Technical_Issues" rel="nofollow">https://wiki.roll20.net/Solving_Technical_Issues</a> It sounds like there is either something wrong with your game on the back end that will require dev intervention, or else your game is too large and the AWS server is timing out on the copy function (which is possible and has come up in the past for really large games). Either way, submitting a ticket should be the way to go here.
