Still really rooting for this feature.
We have walkators (one-way), secure exits (one-way), escalators are separated into right/left for up/down. So obviously, one-way is already supported by trhe pathfinding. But altough People can only go through security checkpoints one way, and require only a single tile/square to move, the stairs and escalators following the one-way secutiry checkpoint must be two-way and 4 sqaures wide… Sure, that makes so much sense // Irony off…
