Steel Ingot Recipe Crash: RailCraft 7.1.00

Game crashed after looking up the recipe for steel within the NEI menu. Left clicked on Steel Ingot after typing Steel into the search bar, and saw the Tinker's Construct recipe for 9 Steel nuggets. Proceeded to click the bottom arrows to bring up the RailCraft recipe, and got the "internal server shutting down" screen.
