So I got a tree farm cart doing it's thing, works great. The cargo manager works great, keeps it fueled, and stocked with bonemeal/saplings. I set up a filter on the bottom of it to pull logs/apples/saplings out, to feed my charcoal and biofuel factories. My issue is, the filter is pulling saplings out of the slot that feeds them into the cart as well as the slot it empties into. Does the cart fill it's sapling slot from drops before filling it's chests? If so it doesn't matter. If not, how do I keep some saplings in the cargo manager to feed the cart?
