Yes I spent about 20 minutes looking for it yesterday when I couldn't get the Driver's Key out (later realised the reverser has to be "Off" not Neutral). That made me so late that after saving and resuming the kaputed timetable bug reared its head - game over.
We are aware of that we have to get better with manuals. We will get better with manuals. We are looking into different ways of getting better with manuals. We released a few (2?) short video manuals. Happy now? We will now resume releasing things without manuals.
