Tora, Master of the Hunt Mission: Reeking Den

Bug Report Reference Number: 3629021625

I got the Tora, Master of the Hunt mission to enter the Reeking Den, a small cave with a bridge leading to a platform with 8 apes and a unique Ape Chieftain that summons totems.

I started fighting and quickly realized while kiting that any time I crossed that bridge again the mobs reset back to their Out of Combat positions... negating most of the difficulty of the mission.

This is still happenning in 3.1.0.

I got the Reeking Den with the bridge / platform, and the mobs cannot cross the bridge, making it easy for a ranger character.
I uploaded a video of the exploit to better illustrate it: https://youtu.be/729k_O2oohQ

Note how the dead mobs are packed at the end of the bridge, and how the boss loses interest in my character every time I cross it.
