Wrong screen name displayed in one specific game.

So I'm having a bizarre bug. Whenever I join a game of a specific campaign, instead of displaying my screen name, Roll20 displays my email address instead. It displays the correct name in all other situations. I'm on Windows 7 64-bit using Chrome. Does anybody have any ideas? (Just for complete clarification, instead of saying "Snooglebum" in my portrait / in the chat of a game, it'll show my email address instead. Which is not ideal)

Might the game in question be one that's hosted on the Dev Server ? I recommend checking both the Dev and Main versions of the My Account page for the display name in question. Regardless, once in game, you can change your in-app  Display Name from  My Settings tab of the Sidebar.

You should be able to change your displayname for a given campaign from the settings tab of that campaign's VTT. This has no effect on your forum display name, or your displayname in other campaigns.
