Unable to Complete Hiding in Plain Sight

Hiding in Plain Sight has a roleplay event associated with it, with characters involved speaking at length to each other to explain and expose story elements. This means that NPCs can be busy for a length of time while this happens, becoming unresponsive.

If you're looking to start this quest, please wait around, as it could be that someone else started it before you, and the characters involved need to act out their roles.
