I just set up a Harvester, and I've followed tutorials online to help me get it to work. Everything is setup correctly, I'm positive. The Harvesters 'idle' section is going up and down, and it is connected to a Lava Generator. However, it can't cut down multiple trees. It only collects the FIRST tree to grow, then it stops working.
Am I doing anything wrong? Or is there something else I need to add?
