Hi, have you changed the crafting method in the mod configuration? Otherwise, it will only give you the blueprint after defeating MacTusk.

hello ! yes dear i have and i have tried everything but i could only get the blue print even when i changed it to Alchemy engine , btw i really love the idea of blue print ! its so nice ty so much but i also have a question ! do this mod make mac tusk to only drop blue print and nothing more ?? because i have killed him and he only dropped the blue print ! no tusk no tam .

Odd. Could be a conflict with another mod, but I doubt it. MacTusk does drop items as normal, the blueprint is only a bonus.
