When you set as a filter in the Sorting Machine some item with NBT and put same items, with diferent NBT data in the chest, the Sorting Machine will start to spill out the items you specified in the filter with the specified NBT. Leading to for example free and unlimited charging of batteries, and other duplications were NBT data is the key.

With this exploit/bug is possible for example also duplicate items contained in containers, such as Backpacks, where their content is stored within NBT.

For easy understanding here is a video from one of the players:

@JasonMcRay I have fixed the BluePower glitches in my BluePower forked repository. See here: https://github.com/Robotia/BluePower

I have also made a pull request just in case the authors of BluePower come back ( #441 ).

If you need a compiled jar, let me know.

@robotia Thanks. I will take a look at it at later date, when I am making another modpack update, which will not be for couple of days.

Please see WIP items for modern versions #466
