After the last update, the option to choose a car in "single race" has disappeared. Only the BMW M1 remains. I have uninstalled and reinstalled AMS2, but the problem remains. Does anyone know a solution to this problem?
Did you, by chance, previously select a ruleset for the M1 Procar Series? I'm not even sure there is one to be honest, but if there is that would explain why your selection of cars is limited to that one. EDIT: If that ruleset is active, deselect it and all cars should be available again.
