I've noticed before that mason leaders sometimes get 'extra' charges without dying, but this is the first time I thought to save a replay. The original mason in this dark heresy game(where Mason Leaders are limited to 2 recruits) ultimately, over the course of the game, recruits two masons and purges three cult, for a total of 5 conversion attempts. He never dies and the Mason Leader never changes. I'm not sure why he keeps getting to recruit after the 2-recruits limit is reached; whenever I play Mason Leader, both purges and recruits count against my charges.
I am not accusing the other player of cheating, as I have seen this behavior in other games previously, where the mason leader would thump, say, 3 cult. I think there's a bug in the counting system that stops him under certain circumstances.
