In the current latest version of techguns the Grim Reaper crafting recipe does not work. It is created using 4 Guided Missile-Launcher and one hardened carbon base but putting these ingredients on the crafting table does not create the Grim Reaper, and I tested both with empty and full Guided Missile-Launchers and even using the JEI mod to verify if the crafting is correct but the result is still not created, now I have 4 unused Guided Missile-Launcher and I feel like an idiot who just wasted material XD
