I there a bug/glitch to duplicate items?

Hey all,

I want to know if there is a way to duplicate items in minecraft 1.7.2. on servers...

I have found a piston dupe glitch but that one was already patched.
And there is ender portal glitch, but I can't acces the ender on the server.

So if you know a working bug/glitch post it @Down

THANKS!!!

Yeah just check out this thread and you will find a 1.7.2 dupe

Oh I see you can't have a post like this...

But i haven't seen an 1.7.2 dupe bug/glitch post yet.. So mby it can be helfull
