Why did you use RebornCore only for registering an one block and it's crafting recipe when you can just use GameRegistry? I don't want to add RebornCore in my mods folder only because of one portal block, and i had to remove RebornCore dependency from SimpleVoidWorld code by myself. By my opinion that's really absurd, small and simple mod shouldn't have any big and complicated dependencies.

If you dont want to use RC dont use the mod.
