I get a random bug once per session with Bartender 4 on Classic Woltk.  Not sure what triggers it.  It has happened when I kill a mob, when I drink something, when I loot something, etc.  It just happens randomly as far as I can tell.

1x [ADDON_ACTION_BLOCKED] AddOn 'Bartender4' tried to call the protected function 'UNKNOWN()'.
