Question About Gameobject Containers Being Active

[NetShira]

Not sure if it's a known bug or just my lack of knowledge... but the Quests "The Howling Vale" and "A Touch of Zanzil" are uncompletable because of what I percieve as a glitch.

Game objects Spool of Light Chartreuse Silk Thread (140911) and Tome of Mel'Thandris (19027) are spawned, and exist.. but not activatable by player characters that have the appropriate quests. However if one uses GM mode, and gets the quest.. the items sparkle and are right clickable (activatable). Is this a bug or something I have installed incorrectly?
