What happened?
5 people remained: Good King, Invoker, CL, Psy and Merc (for Psy). Invoker occupied Merc while CL brainwashed Psy at the same night (I played cult so i know that for sure). Result: Psy wasn’t converted because Merc still guarded him.
What was SUPPOSED to happen?
Occupation procs before Merc’s guard, so Merc can’t guard Psy and Psy is converted to cult.
