I didn't look at your breakdown, but if you just look at the graph, it is obvious that you have the correct setup for this game. Knowing 2 town roles and 2 scum roles makes it really easy to do the rest of the matching by hand and see there aren't any other options.
The real reason this is relevant is that it demonstrates that you didn't worry about it in D1 but you
are probably capable of having checked.
Now, maybe that's just because you weren't particularly present, maybe you just trusted that I'm right (working alone a lot, I never trust myself without good reason, because there' nobody else on hand to spot my mistakes), but it could also be that you weren't interested because scum had more information given that they knew about the set of scum roles in the game.
At least, that was my thinking when I asked you the question. Looking at the possibilities and the graph now, marginalising on the scum roles we now know are in the game doesn't really narrow the possible town roles down that much. That's actually a pretty neat feature of the game design :-)
