That certainly doesn't seem right, when I copy my long running game (nearly 2 years of regular play now) to back it up it takes moments rather than minutes, let alone hours! It is worth running through the standard technical help steps below but if after doing those you click to copy and it still hangs for a while (give it 5 minutes to be sure) then step 4 will be invaluable to the devs to diagnose any potential issues. Could you please carefully work through the first three steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!
