It has happened again, this time producing an error window.  This error was encountered upon reaching 100% completion doing the “Dijaradin Defenses Disrupted” quest. – Edit:  I also just noticed that the lua line numbers in this error appear to be the same as I previously reported.  This issue has to be related to a guide configuration as I am not running any other addons and the installation was clean with a WTF folder purge.
