vote modifiers dont always make it into day posts (will wait for maurice's answer for sure). There was obviously a vote on someone that either counted double, or a vote on ike which is basically like 2 votes on ike. the second vote on hirk tied it. since the OP states that in a tie lynch someone will die, it would be silly of the baddies to tie the vote on one of their own instead of on a goodie (to give them a 50/50 chance).
This doesn't put Hirkala 100% off the hook, but unless Araver is good (slim to no chance imo NOTE THIS TEXAS JACK) then Hirk is good.
