I tried to use a series of dimensional doors to send a chest minecart home from an abandoned mineshaft through a travel hub I'd made in a pocket dimension. The cart hit the first detector rail, opening the door. It went through...and vanished. It was nowhere along the rail in any dimension, it wasn't stuck behind any of the doors, and it wasn't stuck in the wall at the other end. What happened? Where's the cart? :/
