*I apologize if this is a repost, I searched the forums but could not find any other posts about this quest*
This quest, picked up from Laris Geardawdle in Ironforge see's you travelling to Felwood in order to kill oozes and use Ooze Jar's on their corpses.
There are two types of oozes, Cursed Oozes and Tainted Oozes, each with it's own type of container to collect them in. However, I recently discovered doing this quest that it is possible to use the incorrect ooze container on an ooze (for example, I used the Tainted Ooze Jar on Cursed Oozes). In addition, using the incorrect ooze will not cause the corpse to dissapear as normal.
The consequence of this bug is that only one ooze needs to be killed and it's corpse used to collect all six jars of the incorrect type. Not a groundbreaking exploit, but a useful timesaver nonetheless.
