Glad you found a bug to squash! To answer your question, yes, I do turn on the Liquid Water to H2 + O2 electrolysis process and it does produce hydrogen and oxygen (I thought it was producing hydrogen gas, but maybe it was producing liquid hydrogen and that was going into the fuel tanks....)
Refrigerators then receive the Oxygen gas and convert it to Liquid Oxygen, but it never leaves the refrigerator part....
