Project AHO - Start when You want Mod
MODNow updated for version 2, with lots of bumbling around by me and some nifty scripting from AndrealphusVIII (check his other mods).Normal ESP or ESL Flagged versions are available.
If you want to use the mod in your play-through, click the start mod option as you would normally, it just wont start until you have the note.
Alternately you can use additem menu to search for Shaglak's Note and next time you port somewhere outside a city/house etc he should appear. (No refund paid if he doesn't).
