I've stepped in to take care of Bio Industries (and I've also been given collaborator status on the Natural Evolution mods, as I found out today) while TheSAguy is absent. I renamed a lot of stuff (recipes, items, …) in BI, and it seems that this has caused duplicate items to appear (e.g. dart rifle and turrets) if both Natural Evolution Buildings and Bio Industries are active.

I'm working on getting the two mods back in sync, but it may take me some time before I can upload a new version. I'm very sorry for the inconvenience, but as this is no game-crashing bug, I hope you can cope with this for a while. :-)
