I've been trying to change Fort Dawnguard refugee Alvide to a vendor standing next to a small cart. Added xmarker heading for her place to stand and created an AI package so she stands there from 8am for 12 hours (this works fine). Also created a Alvide Merchant Faction with a start hour 8 and end hour 20. I've got the "What have you got for sale?" command, that's all ok but whatever I do Alvide will not stop working after 8pm even when she has gone back to her usual duties.
