So I am on a row of glass and I am mining a row of glass at the 4th lvl above the one I am walking on. Without a pet the auto movement makes me jump over the upper row, then removes the glass & with a pet it makes me jump up till my head is touching the underside of the upper glass, then removes the glass. This changes depending on weather my pet falls off and is no longer close to me. As long as the pet is close to me, I stay under the upper row.
btw the pet is a penguin, my attractor is on.
