Quick question. If the Robber swaps with the a person who turns out to be the Troublemaker, when the announcer informs the Troublemaker to open his/her eyes, is the new Troublemaker (aka former Robber) supposed to open their eyes as well?
This happened to a group of us who were playing for the first time. We ruled that you only do the role once based on what you started with. In other words, the Robber who became the Troublemaker did not open his eyes when the announcer instructed the Troublemaker to do so.
The Doppelganger's the only person to do more than one thing during the night, and most of the time they do the second thing as soon as they discover what it is - the exceptions are the DoppelWolf, DoppelMason and DoppelInsomniac where their role powers rely on waking at a specific time.
