Technically, this is a sheet issue and not a Roll20 issue. The topic has been discussed over here , but the summary is: Viperc46 has sent a pull request
to update the background. The fix should go live once Roll20 updates
the character sheets (which happens on a weekly basis). In the meantime, you can fix this if the creator is a
Pro (paying subscriber) by copying the HTML and CSS and pasting them under Custom Sheet . This is how you would do that. Please refer to that thread for future updates.
