Custom Block Entity with Screen

be sure you are class loading your registration classes are mod init.

normally this is done by adding a method to your class and calling it from your onInitialize method

public static void init() { 
// intentionally left blank. called to force class load
}

public void onInitialize() {
  ModBlocks.init();
  ModItems.init();
  ...
}
