I'm trying to make a custom world generator for the blocks that I am adding to my mod. I've written the code for the generator, but every time I attempt to load a world the game crashes. I've double checked my files and everything looks okay. Any help in solving this would be greatly appreciated.

 

I've attached a crash report and the generator's code below.

Fixed the generators and it works perfectly now. Thank you.
