Multiple Combat Guardians For Goblins At Low-Level (Trigger Unknown) (Patreon)

A bug report on the official forums states that a player was summoned out of the goblin starter zone before completing the quest chain there:

The NPC combat guardians that you acquire very early in the Kezan quest chain,  Izzy, Gobbler, and Ace, apparently spawned with the poster in Azeroth and now follow the player everywhere. 

These NPC's normally aid the player in combat-the player does not confirm that they do this in Azeroth but it is a fair assumption. This would significantly speed up leveling on the main continents. 

Presumably what has happened is that the player still has a quest in their log which requires the three helpers. The game code never allowed for the possibility that the player would leave Kezan so Izzy, Gobbler and Ace will spawn indefinitely as long as the quest remains in the player log. 

I am testing this currently and may add more to this article.

EDIT: myself and others have had at best inconsistent results whilst attempting to reproduce this (see comments below). Expect frustration.
