I found Why Mafia lose , because of Claims .
If GF claims Sherrif when Janitor claims cit , it can be very difference . Why ?
1) Think kills go same and Evan didn't check Janitor claim at Night 2.
2) GF bus Consort like game .
3) After kill Invest , Sherrif (GF) bus another Mafia in the following day , or at the following of following day ( Day 4-5 ) .
4) Sherrif Instantly confirmed via bus 2 Player , who has an easy win . Mafia can kill Doc and vigi at following days , Which give Mafia 2 Kills + 2 Mislynch .
Obviously it is hard to see that at the time of Mass-claim , but at least this can give us an Idea About who should claim what In a Mass claim later .
