Crafting System with Different Crafting Methods Options

[lightingft]

Hello everybody, so I need a crafting script which would support different crafting methods. For example, Weapon ID 1 is Iron Sword.
You can craft it with for example 3 ways (OR MORE):
With Item ID 1 - Iron Bar
or
With Item ID 2 - Recollected Iron
or
With Weapon ID 1 - Rusty Sword and Item ID 3 - Rusty Metal


Just an example. I tried PrexCraft, it's very great but if I add different methods, then you can duplicate the item... So I am requesting a Crafting System, or a MODIFICATION to PrexCraft to support different methods.


Thanks in advance,
~Lightingft.
