Due to how you handle etching acid it does not have a render in tanks etc., shows as back and purple checkerboard. This normally is just a bit odd looking and not an issue however in TFC the barrels, which can store fluids, it causes a crash because the fluid can't be rendered in the GUI. Could the Icon be handled like it is in BlockFluidPneumaticCraft.java?
