Realm tested - Pandawow Fun(probably happens on x100 too).
Date - 27/09/2015
Spell/Creature/Item - Custom server NPC arena spectator and his system.
Description - Using .spectator leave and other commands do not work at all, even with the addon, thus making you wait the entire game to end, which sometimes may take up to 10 minutes.
How it should work - Upon typing .spectator leave, the player should be teleported to where he previously were.
Priority - 6/10, you can just relog.
