Waterdeep: Dungeon of the Mad Mage (No Monsters)

So I purchased the titular adventure Module to play on Roll20 seeing as one of our players is moving across the country and thought this would be wonderful tool to use to help with speedy set up and looked around it and it all looked awesome, but I logged in today to find all the monster tokens have vanished from the maps. Is there a fix for this?

Some things to check: 1. Make sure you are on the token layer. Other layers may cause tokens to appear grayed out or to disappear. 2. Did you buy any chance purchase a module and a separate token/map pack? Only one or the other is needed, and installing both can lead to unexpected results. You can write to <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a> to negotiate a resolution/refund.

I'm not sure what happened, but I just remade the campaign and it was all back in working order. /shrug Hopefully just a fluke.
