Strange Image Appearing On Top Left Corner of all Maps

This little... thing... is on all of my maps on my edge of the empire game. I have no idea what it means or why it's there.

Hi, Chaos Cowboy. Sorry you're having problems. Have you tried different browsers or re-starting to verify that it is not a caching issue? If it persists, p lease 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!)
