This issue has been persisting for a long time now, but if i exit the scenario, reselect the mode, it still keeps happening.
If you gave some examples other people could also look at the problem. Saying "something happens on some routes" it not very clear
Find the Scenario and there will be a ScenarioProperties.xml file. Open that with Notepad - its just a text file then towards the bottom you should find <SimpleControlsOnly d:type="bool">0</SimpleControlsOnly> <ExpertControlsOnly d:type="bool">0</ExpertControlsOnly> Make sure that the value is 0 - if it is 1 then overwrite it it should stay at what you select.
