Hello Arthur, I'm sorry to hear that you're having issues with the site. The Shaped Sheet is a third party sheet, so Roll20 is a little limited if the problem lies within the sheet itself (though this is pretty unlikely). My guess is that you are either using a connection that has become slow or unreliable for a time, or that something might have gone wrong with your session. 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!
