Actual Behavior

Issue description:
I am playing FTB Continuum. After building the storage scanner the client crashes after trying to manage my storage with the storage scanner. Unfortunately I am not able to start my game again, because it is now crashing on every start. After contacting McJty it seems to be a problem with the Engineers Workshop. So I also post the crash report in this board, hoping for a solution.
