Duplicant motion sensor range incorrect when sideways, maybe related to oil refinery

The cell of interest on the refinery is the second from the left (on the automation port), even if the dupe moves to the right, it is actually standing on the automation port. The dupe is not in range of the sensor. This is working as intended.

A quick tip to find out which cell is the cell of interest: it is typically the cell of the building that the mouse is hovering over when you are trying to place the building for construction.

Thanks, today I learned something.
