Reporting this because of the recent changes. It is not a real problem.
Running a script that was adventuring in the Haunted Library. Relay browser had not been opened. Got one of the choice adventures.
I clicked on the continue link, browser launched, saw some weird stuff almost like it was trying to display the main screen inside the central frame. That resolved itself to the choice adventure I was expecting.
 The Haunted Library
Encounter: Lights Out in the Library
Manual control requested for choice #894
choice 1: Get out of the Library
choice 2: Grab a Candle
choice 3: Ponder a Quaint and Curious Volume
Click here to continue in the relay browser.
I think the debug log was generated between the time I started the relay browser and the time I made the choice, but I am not certain.
