I've been playing the Voltz pack lately and decided to go into creative to test out a lot of the features. One thing I wanted to test out was the forcefields. And since I dived right into it, I had no idea what to do, so naturally, I turned to youtube. While looking on there, I noticed that each video needed the use of an extractor. And as of, as far as I know, 2.0.4, Extractors are no longer in the game. I have no idea how to set it up now. If anyone would be kind enough to explain what to do or link me to a place that has this problem solved already, I would greatly appreciate it. Thank you.
