FYI This does not allow you to loot scientists, murderers, and zombies 

still unable to loot NPC's

Any updates? 

By now it's possible to loot the scientists as long as one skins/harvests their bodies. Is there a way to either convert a dead scientist body directly to a lootbag or some other kind of fix for this? 

Nope sadly

The weird thing is, we've been playing on a server which I'm pretty sure of was running the same plugin. Else I would need to look out for a different plug-in :(

This has been added/fixed.
