Slightly tweak the dragonskin vest.
Migrate MBR Vests with Kevlar plates to the MBR Vest Empty.
Add recipe for Hard Steel Plates to the same books as Hard Steel Plating.
-It was previously possible to craft Steel Plating and Steel Plates, but only Hard Steel Plating from a book.
-Steel Plates require half the materials of Steel Plating. Hard Steel Plates thus require half the materials of Hard Steel Plating.
