Go check your snagit file an make sure there isnt any added shit that states that it should dump non perfect gear.

Past that I can't remember what could have happened to make it ditch a NW.

(Noone would set a bot to pick something up that they don't want, just to sell it later. They would have just excluded it from the snagit file, and saved the inventory space for wanted stuff. At least I don't think)
