A simple suggestion, that might seem too powerful, however I think it should be allowed for the Lookout to watch their own house, and see who tries to visit him/her at night. If a Lookout/Detective were to view 'em, I guess it would say they did nothing that night, or that they visited their own self. This would also prevent the Mass Murderer from possibly killing him/her if they were to visit their house, since the Lookout would obviously be outside of their own house for the night. (Still think SK/GF should be allowed to kill 'em, however.)
Yes, no, maybe so? Only seems rather reasonable and fair, from my point of view.
