The last time I saw a situation like this with a mod of my own, I used Player.moveto to go where the NPC really was, and the map marker turned out to be accurate. Does your NPC move between locations at all, or is it all supposed to happen at Aleswell?
In my case it was a wander "at Editor location" that should have been "at current location" and the NPC had been created elsewhere and moved to the desired location later. So whenever that package came up, the NPC went "home".
Unfortunately no, she never leaves the confines of Aleswell, and her editor location is set inside her house there.
I'll recheck her packages again to be sure, but she does not even have a wander package running ever, all of them are travel packages to specific locations within aleswell.
On a side note, what do you guys think?
If I removed the quest marker, and just left the quest update info? It does clearly state she can be found in Aleswell, and her store is easily found there too. Further more there are a number of quests beyond that which send the player back to her in Aleswell, and again, wondering the validity of even bothering with the quest marker, as everyone already knows where to go anyhow.
