There is a glitch with the combiner that i have discovered.
When crafting packed ice, needing 36 H2O per crafting space, even if only 1 crafting space has 36 H20 but the rest have only one it starts crafting and doesn't consume any H2O. It just infinitely crafts the ice. I don't know if it works with any other recipes.

Almost done with the next update (which has a fix for this).

Ah, my mistake, I'm sorry i saw Chemlib on the chemicals and thought the combiner, etc were in the same mod. I will close the thread.
