I modeled it using an agv elevator.
It's perfect from the second floor to the third floor.
However, on the way down from the third floor to the first floor, the elevator arrives on the first floor and AGV exits the elevator, but then exits the elevator after crossing the Straight Path again.
This may have been my mistake in setting it up.
Is it a bug? Otherwise, I'd appreciate it if you could tell me how to solve it.
