RG Live WotLK 3.3.5a

While doing the quest Drake Hunt there are several mistakes.
After using the item Raelorasz's Spear the drake should be binded to the player with a visual rope should attack the player until the aura Red Dragonblood disappears. After that he should get the second aura Subdued. The aura of the dragon should have also the duration of 3 minutes. On our server the drake flies to the player after the first aura disappears, he doesn't get the secound aura and there is no visual rope between the player and the drake.
There are too less Nexus Drake Hatchling.
The aura Drake Hatchling Subdued has a duration of 3 minutes. But on our server the duration never ends. It is shown that the aura disappears after 3 minutes but the counter doesn't sink. After the aura has disappeared the drake should die and the aura on the drake also should disappear. The timers of the drake-auras are working normally.
The event when the drake comes into the transitus shield is completely missing.
The quest can be done, but it's cancer for the eyes^^
