Hey guys, not sure if this is the right topic for this but I was wondering about the item drop/pickup when an NPC is killed - why does the NPC (like Stingtail's pyro skillbooks) not drop everything he has - especially after doing a trade and seeing the skillbooks, then killing said NPC and only receiving either what you traded previously or one or two skillbooks?

Just curious on the mechanics of that, and whether it should change or not?

Personally I would say for "realism" sake drop what you saw them selling (whether or not you have a bad rep with them or not) - but I also see the downfall to it being that why even have an NPC when you could just kill him for the skillbooks and not even worry about caring about the NPC's story...
