Minecraft Version: 1.12.2

I crafted a Railgun and put it in my inventory. After adding the Railgun to my Transmutation Table (ProjectE) my game crashed and it crashed every time I tried to open the Transmutation Table GUI until it got removed from the ProjectE-learned-item-storage (or however it is called).
Though it is caused by ProjectE I think this might not be directly related to it but rather the displaying of the item which might happen in any other mod doing equivalent things. Either way I hope this isn't too complicated to fix.
The line causing the problem is here and because it is the energy of the item I would suggest an energy default value of 0 if such an exception is thrown.

Here is the crash log
