if you set up the pipes in a certain way in game you are able to duplicate ANY item as long as you put 2 of the same in there , also if you put any item in there with durability it will give you a full health item even if its 100 percent broken

I am aware of a way to do this and have been working on a fix. Can you pm me with how you have set this up so I can confirm it is the same issue.

sure , i did try and pm you but it wouldnt let me 

Try now.
