Mafia claiming Mason?

[Thoth]

In Asterix mafia my scum group claimed to be masons. Of course that's in a Phoebus game where there usually are multiple mason groups. I disagreed with the proposal during the night, but when the other 2 went ahead with it during the day I had to cooperate of course.
It actually worked pretty well for a while until we suddenly both died in the same night.
