it's entirely possible i clicked the wrong option, which brings me back to the initial question: is there anyway to fix this, be it with cheats, save editing, or something else.
The first thing to do is open the Console with F12 and check
flags["FOLLOWER_LANE_INTERVENTION"]
flags["LANE_FULLY_HYPNOTISED_FOREVER"]
If INTERVENTION isn't 'undefined', it shows the crewmember that intervened.
If HYPNOTIZED_FOREVER is 1, you got the Crew intervention scene, but told them to fuck off.
Setting then to 'undefined' should give you another shot. If you're using a JSON editor, deleting the flags will probably work.
You could also mimic a successful intervention with
flags["LANE_FULLY_HYPNOTISED_FOREVER"] =undefined;
flags["PC_PAYS_LANE_ERRY_DAY"] = undefined;
flags["LANE_DETOX_COUNTER"] = 0;
