I was wandering around one of the game's dungeons, and I found a "Staff of Tagfieran Healing" lying on the ground. When I attempted to pick it up, I got a message saying "You are unable to pick up this object, but as you touch it a powerful spell is cast on you." At this point, the bug comes in to play, because whatever spell is supposed to be cast on me isn't, instead a message pops up in the corner saying "My skill level is too low" as if my character were casting the spell. Thing is, I have no clue which mod this object belongs to, thus who to tell about the bug. The search term Tagfieran has only yielded an RP discussion on the Nexus.
