Talked with the user - they said the error screen stopped happening when they reloaded their game.

That, combined with how CI would catch any syntax errors in existing PRs, leads me to believe that this error came about as the result of a networking issue - some data got lost while transmitting the javascript files, and resulted in this.

So I'm going to close this. I've given the user instructions to let us know if this continues to happen, or if they notice anything off about their character prefs.
