What happens if two wolf kills are targeted to a huntsman's target?

Solution 1:

Both wolves would die in this scenario. Any other attackers from other factions that are vulnerable to the Huntsman's defence would also be killed. Vulnerable attackers include Warlocks, Ghouls and Voodoo Doctors. The Huntsman also would protect against an additional Vampire attack, but the Vampire would not be killed by the confrontation.

This is because when the morning starts attacks are resolved "simultaneously" - as the game acquires more interactions this may not be desirable anymore, but it certainly isn't changing in the short term.
