So, I have a liquid storage room with 4 max-sized railcraft tanks. Each tank is connected with a fluiduct to 2 ender tanks, one for input, one for output. Everything was working fine for some time, however, one output ender tank has suddenly stopped receiving fruit juice, and another ender tank has stopped sending lava. WAILA tells me that the fluiducts ARE filled with fruit juice, so the problem isn't on Railcraft's end. I have made sure that the fluiducts are wrenched correctly and the ender tanks are in their correct modes. Any ideas?
