Just thought of something Kari once mentioned to me about him discussing game balance with Rabla and some other people.
Kari said in his games the witches want less day Phases and the humans want more. Hence if a witch got modkilled, as an additional punishment to the witch team he said he would continue the day phase and give the humans their lynch. Conversely, if the humans were modkilled in the daytime he would end the day phase with that death. That way no one would “tactically modkill”, E.g. If I was a human and was really convinced I was going to be voted off next game’s second day, I could modkill myself (with permission from the team, of course) saving the human vote for someone that could be a witch.
So considering that, either Rabla disagreed with Kari (far more likely) or it really isn’t a modkill…
