Using Immersive College of Winterhold, every morning the instructors conduct "class" and part of that is Phinis and students casting conjuration summons. At some point the casting of these summons causes reaction in every NPC in the room. "What in the world!" or "This cant be happening!" are some of the NPC comments as they all react and stop lessons for a while. Last time Colette moved toward the summoned atronach only to become permanently stuck in about the spot where Ancano messes with the Eye. I am using Apocalypse, Odin and Triumvirate spell packs.
This is such an odd thing I have no idea how to figure out the cause so any input would be very appreciated.
