Added a new dupe fix, which allowed players to dupe rails of all types, carpets, and such. This version will REMOVE the piston causing the dupe thus breaking the dupe machine, the location in the world will be written to the console so that you can locate the offending player / machine.
The protocollib / recipe command feature of this plugin has been removed since the /recipe glitch was finally fixed. There are no config changes if you're upgrading from an older version.
