I was trying to connect AE up to my soul sand and mushroom farm. I wanted to drain the sludge out of the harvesters, and no matter what I did, the fluid extractor would not work. Since this was my first time using extra cells, I thought I was doing something wrong, so I checked out a mod spotlight. I had everything exactly right, it just wasn't working. I went and made a liquid interface to try piping it in. I connected the fluiducts and that didn't work either. Still no fluid in the AE system. I gave up and went to work on something else. In my way to my AE terminal, I swung by my farm, and found that I never finished connecting the AE lines back to the controller. I had brought them into my soul sand farm, but never connected them to the rest of the network.
