[REJECTED] to old friends quest bug

Bug description: You got the quest objective order wrong. You have to first kill 50 plants, then enter the cavern, then kill the Botanist. ^.- Additionally, the NPC needed for the quest is spawned a few places during this quest (npc finder says there's like 3-5 spawns of him, including the final quest objective), but he should not be killable. He should vanish and taunt you as you kill his plants, you normally won't kill him until you reach the one in the cavern (this one works and will give credit, the others will not, which is normal).
Proof: Check your own link, and compare with what you see here: http://wow.gamepedia.com/Quest:To_Old_Friends
