I am trying to get into forge modding, and I have a semi functional mod. it is based off mcJTY's youtube tutorials, and i am trying to implement a generator that consumes diamonds. However, whenever I try to access the GUI, the game crashes with the following messages in the server crash folder.
(here is my source code) I believe the problem is in src.main.java.com.Uebbels.MyFirstMod.blocks.FirstBlock.onBlockActivated()
