Disabling Custom Fluid Pipes in the cfg makes the Simple Washer uncraftable. The Clay Pipe in the recipe is replaced with an Error Ingot.

To-do: Implement better flexibility and checks. I'll submit a pull req.

This is why the error I got exists. So that things like this get flagged. If you just wanna check the config during washer loading and use copper alternatively, were sweet.

Sure thing b0ss

@Rongmario Where are we with this?
I will fix it today if you haven't gotten around to it yet.
