Could you provide some screenshots of the issues you were experiencing? I wasn't able to reproduce them on my end. The biology pack is indeed a crafting recipe... you have to unlock it through research, and also unlock its pre-requisite research first.

If you can send the screenshot, then I'll take a look as soon as I can. Thanks for reporting!
so in this specific case i have an inserter going to a box and then another inserter taking from the box into an underground tunnel, however the second inserter isn't taking anything for some reason, it just empties the box.
P.S I have discovered that the crafting materials needed for something randomly changes, sometimes crafting a furnace costs 2 stone sometimes 10 and sometimes 5
