I would prefer to wait a bit more, since I'm still waiting on a couple of PMs, but I'll post some of my thoughts here.
I am pretty sure that mathman is an FG. This is partly because he have claimed two different roles during the game, and partly because of some other stuff too. I might die this night, and I don't think all of you are online to change your votes now, so I would definetely advice to kill him next turn.
Another suspicious individual is Calindu, mainly because mathman have claimed that he knows Calindu is innocent, and that they seem to work together. Also note that they voted the same.
So I believe that mathman and Calindu are the remaining FGs. I am not 100% sure of this, but it is so far the strongest lead I have. If mathman is not an FG, the 1world should be one, because they claimed the same role.
This is what I know right now, I might update this post again before the deadline.
Calindu (4) - Mort, 1world24, Annele, Fippe94
Mort (3) - Calindu, mathman101, Kuroaitou
