Curse of Strahd bug (possiable spoilers)

Today my party reached the werewolf den. The map freezes my browser and the browers of my players. I tried diffrent browsers like internet explorer. Firefox and chrome all three had the same effect. They froze up on the Werewolf Den map. I had used this map before it seems after the recent update of CoS’s maps is when this started. 

We're sorry to hear that you are experiencing issues with this. Please carefully work through to 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. Step 3: Clear your cache If none of the above succeeds, thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you!
