Upon initial load the Plant Interactor works fine, be it newly placed or already present in the world. Once I quit to the title screen and load a save the machine fails to harvest any crops, block updates or breaking and replacing do not help. The machine continues to animate its progress bar and appears to be consuming 4RF every time the bar fills.
