Given all of the complaints, I think that Crystalline Blackrock should be dropped in players' backpacks and not stay on corpses to be looted. I also find it quite hard to loot the mess of corpses for Crystalline Blackrock, not to mention also, that selective looting scripts can be quite an unfair advantage to those using them at the expense of other players not using scripts. My understanding is, that selective looting scripts might be so easy that just walking by corpses with the script running could ensure that all wanted items might automatically be looted by the script without needing to have to bother opening the corpses up, shuffling items around and so on. Did Crystalline Blackrock drop on backpacks, instead, this inequality would be dealt with since players would not need to loot them on the corpses. At least, that is how I see it.
