I saw this symptom with extended, so I checked with standard and confirmed that it has the same bug.
Confirmation procedure:
(1) Open the mini-map. Then press the networks button. At this point, the networks button is sane.
(2) Open the line management dialog. Then select the line that has the schedule. The line dialog opens and the network display in minimap works properly.
(3) Click the Networks button twice. He turned off the netwroks display the first time and it never worked again. (´・ω・｀)
He will not perform any action unless the line dialog comes to the forefront.
When the minimap dialog is active, only disabling the network display is allowed. This behavior is strange.
