...which apparently does not work at all. This is Blood Magic in Agrarian Skies 3.1.2. I was experimenting with liquid management in order to automate some crafting processes in the blood altar. Pumping life essence out works perfectly, if painfully slow, but when I set my tank and duct to get the life essence back into the altar, it does vanish slowly from the tank, but never appears in the altar. Also, if I remove the portable tank I'm left with a fluiduct full of life essence which doesn't go back into the altar. Is there something I am not understanding about the process? Do assume that I know how to pump fluids with TE fluiducts and portable tanks, and that the altar was not full while I was trying this.
