That's an unusual problem, so I suggest trying some things to isolate where the problem is occurring. I'll place the standard troubleshooting steps below the line; some of them you've already done. In addition, you can try: Creating a new campaign with the module and trying there. If it works there, that means we've isolated it to something specific within your current game. If you have not yet started the campaign, this would also be a one-stop fix. If you have started it, but have not done much modification, as a Pro user, you can use the transmogrifier to move in the PCs. Try doing dropping a character while logged in in a private browsing window Finally, since this seems to be a common mistake in CoS, make sure you haven't loaded both the module, and the maps and tokens addon. The latter is already included in the former, and adding the addon to the module can overwrite all kinds of stuff. Your only option in that is to create a new instance of the game, and seek a refund on the addon: you don't need it. Could you please carefully work through these 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. 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!
