Dig Immediately Outside Airlock Unreachable

When an airlock is placed, no matter what kind of door it is, the game processes that door is a solid object whether its opened or closed. Duplicants can obviously pass through it if its opened but they do not stand in it as they read it as an object similar to a wall. The selected dig block is unreachable because the duplicant cannot stand in the airlock or stand on the ladder to keep the airlock open and complete the task.

I don't think that's quite it. The dupes had no problem digging out the lower block, the navigation clearly shows the dupes know they can stand in the airlock, and the problem continues even if there's flat ground on the near side of the airlock rather than a ladder.
