Specifically the Liquid Gas bottles from Gen's Materials, even more specifically liquid hydrogen and liquid oxygen bottles to go into the evaporaters on a station. I cannot get the code to work when I put it into the hydrogen evaporator. I've tried Hydrogen Evaporator [TIM LIquid Hydrogen] [TIM liquidhydrogenbottle] and I get nothing they won't pull peroid. I just don't get it. HELP!
