What Yaschur said is that he was in the block on the first night. And if on the first night he went to kill Balzac, and not Grande, and this night the murder of Balzac occurred (even if it was a stolen kill), then the clue pointing to Yaschur is incorrect. If Grande was killed on the first night, or this night, then I'm ready to vote based on my deduction. I haven't found any other plausible options yet.

And one more thing. Since a stolen night kill is displayed the same way, theoretically Medzh could be Balzac, who killed on the first night, and this night was in the block, while the maniac killed him with a stolen night kill. This possibility cannot be ruled out.
