One Night Werewolf - DAY ‽

Well actually I was the doppelganger and became a third mason (what happens if there are 3 masons because of doppel, does the doppel see the masons but the masons don't see the doppel, do all 3 see each other, or does the doppel just not have a power then, also when does doppel insomniac happen, if it is as soon as he steals it then it is a bit useless so does he also look at nights end, if so then why doesn't doppelrobber work at the same time as the real robber. I still don't fully understand the doppel role)
