One of my ZNR fields has stopped working, I cannot select a loco,
I have tried deleting the ZNR field and restoring it in the track editor, no improvement.
The feedback associated withn the ZNR feild is functioning normally (ZNR feild turns red when occupied).
But when I touch the ZNR field no loco icon appears in the top box.
All of my other ZNR fields function normally.
