NPC Linkpearl not glowing when class-specific quest is available

[Umo]

I am glad to see that Magnesium02 and ShadowedIce were able to provide information that may prove to be helpful (thanks, Magnesium02 and ShadowedIce!). When you have the opportunity to, please post whether or not you were able to resolve the matter by following their advice.

I can't try it out because I've already accepted (and completed) the quest. Feel free to close the thread or leave it opened so I can try it out whenever I reach another "class-specific level quest" and post the results here.
Anyways it seems it's working that way for everyone (thanks to buritoslicer for posting too!), so I guess it's not a bug and I must post a suggestion on the right section for changing that...
