NPC name: Anden
Quest: Every Anden of the Rainbow
In the final dialogue for Anden's quest Every Anden of the Rainbow, he says "It's been quite awhile" (underlined in red in provided screenshot). This should read "It's been quite a while".
"Awhile" means "for a while." When used like "quite awhile" it reads like "quite for a while" which is grammatically incorrect.
