Pandaria Tree's Company Quest

Hey there, decided to pick up WoW again and decided on the Warmane Private Server. As I was questing with my newly made Draenei, I came across a glitch on Traitor's Cove at Silvermist Isle. The quest was Tree's Company, in which I was supposed to eavesdrop disguised as a tree. The only thing I'm supposed to see as I arrived at the location is the Naga Flag, however a goblin supposed to appear later, Geezle, was also there. I watched videos, making sure that this wasn't supposed to happen, but he IS there so the quest can't be done. Please fix this when you guys happen to have the time because this is a low level quest and new players might decide to switch server or even game.
