Ok so I decided to put together a steve's carts tunnel bore in creative mode to see if they are any good. After the 7 hour(!) wait i'll be able to test it. Thing is, I just realised that there's no way for it to put the loot into an ender chest, meaning the cart will eventually fill its inventory and stop. Clearly this isn't the 'set and forget' system I thought it would be. So what's the easiest way to collect the stuff from the carts inventory?
