I know I’m very late, but maybe use the interface info text script. When ever you get a switch, you receive a token, and you go to the quest-giver (Whoever gave the quest) and it updates the quest to “1/4” or “2/4” etc… OR, the shorter way, is when you get a switch, just make a line saying;
interface info text becomes “Switches 1/4 activated” or “Switches 2/4 activated..”
