Strongly agree with Yeti. In addition, this sets a really bad precedent for future mafia hosts. If your game is stalled, it is ultimately the host's responsibility to finish it, and they shouldn't have a "get out of jail free" card in the form of letting outsiders host their game. If they don't feel confident in their ability to do so, then there is no shame in just abandoning game (provided there is still eventually at least a postgame).
