Issue
Putting Obsidian into the Melter will give 288mB of Molten Obsidian but casting it to make Obsidian takes only 144mB of Molten Obsidian.

Thanks for the report, that does indeed look like an exploit :)

@NillerMedDild In the latest version of E2, this recipe is completely removed, is this intended? Melter should still work, just give 144 instead of 288mB afaik.

Yep that is intended :)

But why? Why not just make them give 144mB?

Because I didn't think it through :P
Hopefully it'll serve as a notifier for people using the exploit that it has been removed, I'll readd it next update :)
