Foulweald furbolgs inflicting multiple diseases...

...even after death!

I am on a level 22 NE druid going through the quests in their areas right now and found a strange bug. While fighting these mobs, you can be infected with a disease that lasts for three seconds and reduces a stat by 10. However, once they're dead and looted, if you stand on the corpse you are continuously afflicted with the diseases until you move off of the corpse. This should not happen. My initial guess here is that an aura isn't being removed when the mob dies.
