1) 0.5.12a (as far as I recall)
2) Windows 8.1
3) Ending is bugged, got 10 identical characters, each with same name, stats, traits, portraits etc.
4) I think that I pressed "1" to move between events. Maybe causing the ending script to go multiple times, giving me said character multiple times? It did repeat each scene multiple times.
5) Time to make each of them obedient and abuse their "Authority" trait, have everyone be obedient forever. Unless that doesn't work.
