I noticed this when watching my pve kill tasks; kill 15 humanoids, 15 animals, 15 insects etc. Some of the Musslaklan npcs on the southern camp of the beach in Aegir's Landing (Uger's camp) do not report as humanoid, and satisfy the "kill animals" task. At least musslaklan digger mobs are affected. If I detect others I will append those mob types here.
