Mafia 54. This is where caravans are robbed!

Saba is executed based on a note from the second night, which supposedly states that Soldier 4 wrote that Zubr was a merchant and a murderer – supposedly, Saba. If there are any other reasons, explain them to me; I don't see them. It's quite possible that the Mafia is actively involved in the execution, taking advantage of the inactivity of many players.
I know what this Mafia is missing – a table. I'll create one now; maybe it will help you understand that you're all noobs.)

Evil

Hmm, I think I was too hasty in assuming that the table might clarify anything. Besides, it doesn't claim to be absolutely accurate because many neutral roles could theoretically belong to Evil, and the neutral roles of the caravans could also belong to the Fourth.

I reread the discussions, and nothing became clearer; I'm going to sleep. Count the votes, someone.
