d2jsp prob

I started running d2jsp a couple days ago and it seemed to work great and all but then i was watching it not long ago and it killed diablo and found a unique spired helm.. i was hoping it was nightwing and it was.. and it had it in its inventory.. and went to jamela and id'd it.. it was 14% and it sold it.. why did it sell a 14% nightwing? dunno if there is like some requirement for what items it keeps or what.. (me don't think g00d) but if someone could help me i'd really appreciate it ^.^ thx..
