I see what you're saying about the Spy, but if you go here: https://epicmafia.com/role - and type in Spy, and click the little icon, it doesn't say he visits. But if you type in "Mafia" and click the little icon it says he visits.

night visiting role: yes. presumably, he leaves his house to slip a note under his target's door...or whispers seductively in their ear while they sleep.
Yes it is a night visiting role, but presumably just to make a kill like any typical Mafia member. The spy doesn't leave messages at night, he leaves them during the day.

What I'm saying is, the Spy doesn't HAVE to visit anyone.

You guys should really try out EpicMafia. The games are super fast paced and get done in minutes sometimes, especially this setup. Which is why I kind of "jumped" to conclusions. I'm just used to the way this setup is played to get a town win.
