Playing the mod for the second time, I just spent an hour or so killing spiders in the Barrow Downs just because they are there. They are quite tough as I'm only at level 14. Anyway I had killed most of them and went back to Stone city to heal. While I was there I thought I might as well train one level. When I came out again all the spiders I'd killed were back and then I remembered that there is a quest (which I hadn't got yet)to kill them all within a week. So I realized I had been wasting my time anyway because they would all reappear when I subsequently got the quest. Perhaps I'll remember when I play for a third time!
