While looking through the list of things various items could be crafted with using the optional components, I came across two things that I'm curious about. 1: Cryo Grenade allows us to add a Fire Gland to it. LOL? I'm guessing it's supposed to be Icy Gland but long hours and eye strain do dirty things to people. 2: None of the plates for the various frames allow the new optional components except for the Arsenals plate. The tooltip says we can add the following optional components: Claw Shell Fragment, Fire Gland, Cornea, Brontodon Ivory, Brinewyrm Goo, Poison Gland, Ink Sack, Space Manipulator, Drone Module, Hypercapacitor, Explosive Device, Culex Wings. I can't even imagine.
