I was testing some stuff with Mekanism alone and it crashes when I built a steam turbine, looks like it won't run without IC².

If you're building from source, you can get around this by copying the IC2 directory from src\api\java to src\main\java

Well I just included IC² in my testing pack, it's easier.

up to you, but you only need that api.

Fixed.
