I wanted to play along the unmarked quest "Nectar Collecting for Fun and Profit" but found that Lesko's house was counting me as a trespasser. I know I can leave his shack quickly, but this small possible error just got under my skin. I trimmed the quest script line that flags Lesko's shack as owned and can now say that Lesko will not attack the player for entering his shack after completion of the quest Those!.

Issues:

-the only real issue is that Lesko's house is not owned, so nothing in his house is marked as his. might try a bit of editing another time.
