Hello, After loading the an autosave from the previous factorio version the scenario throws following error: Error while running event level::on_configuration_changed __base__/lualib/quest_gui.lua:236: attempt to index local 'hints_list' (a nil value) stack traceback: __base__/lualib/quest_gui.lua:2...

Pretty nice. But I wish a feature for the train network to create groups for trains that share together the schedule and the color. Also if you can create color groups and save them instead to pick/copy it from a different train.
