I have gotten quite stuck on this one. I am running Industrialcraft 2 experimental for Minecraft 1.7.10, and the regular cells have been replaced with universal fluid cells. Well, I need compressed air for my blast furnace, and I don't know how to get it with these new cells. I have already tried putting an empty universal fluid cell in the compressor like I used to do, but I couldn't even put the item in the right slot (or any slots for that matter). I would really like some clarification about how to do this, whether I am doing it wrong or I am just encountering a bug. Thanks.
