On editing my route, but keeping my existing session. But deleting my consists and making new ones to drive. I found on a driving session, some of my consists had decided to go on Auto Pilot. or as it said Automatic schedule not player controlled. I did not select this setting, do they go on automatic above a certain number of consists now. Bit of a problem sort of, as they get stuck, derail randomly. Travel backwards as well. I get these little messages all the time, driver is stuck, or has derailed. Sometimes partly rest of consist carries on its own merry way. Just wondering why this has started happening.
