I'm no expert on ProjectRed's Transportation mod by any means, but from what I have been searching online and form using this mod in the past, putting the extractor chip in the routed interface pipe connected to a chest to make it the "return" chest just isn't working. I've tried multiple configurations on the chip (the item responder as well) and no matter what the items will not be taken from the chest and sent back to the system. Am I doing something wrong? Can someone give me a good explanation of how to set up the return chest? Or could this potentially be some sort of bug involving something such as one of the chest sorting mods. Thanks!
