Here are the results, colored in:
N1:
Yellow: ash, Awaclus, chairs
Blue: DatSwan, Galz
White: Space
Red: EFHW, Haddock, gkrieg, schadd, e, Jake, Dylan, iguana, WW, silver
Right colour right place: 7
Right colour wrong place: 7
Ash, Datswan, Galz, Space, Gkrieg, schadd, Iguana are all gauranteed incorrect placements.
EFHW, Haddock, e, WW, silver are all correct placements. So we need two more.
If mafia is yellow and chairs is mafia, that would make Awaclus, Chairs, and at least one of [Jake, Dylan] correct. That's at least 8 RCRP. So Chairs cannot be mafia if mafia is yellow.
If mafia is blue or white, then all correct placements need to be in red. That would make Jake and Dylan town and mean that Chairs must be mafia. However, in that case, we can only get to 6 RCWP. So Chairs can't be scum based on N1 results. And I would argue that the N1 results are the least likely to be messed up.
If one of [Dylan, Jake, EFHW] is mafia and mafia is yellow, that gives the correct results.
If one of [Dylan, Jake, EFHW] is mafia, mafia is blue, and I am white you can only get to 6 RCRP, 6 RCWP. If I am blue and mafia is white, then we can only get to 5 RCRP.
So N1 results clear Chairs, and leave Dylan, Jake and EFHW as mafia candidates. And mean that at least on N1, mafia is yellow.
N2:
Yellow: EFHW, DatSwan, WW
Blue: Dylan
Red: ash, Haddock, Awaclus, gkrieg, chairs, e, Jake, Galz, iguana, silver
Right colour right place: 7
Right colour wrong place: 5
Guaranteed to be wrong: DatSwan, WW, Awaclus, Gkrieg, iguana
Guaranteed to be correct: ash, Haddock, e, Galz, silver. So we need two more.
If EFHW is mafia and mafia is yellow, then Chairs, Jake and EFHW are all correct. That's too many RCRP.
If Dylan is mafia and mafia is yellow, then Chairs and Jake are correct. That's 7 RCRP. Then you can switch Awaclus with Datswan, Gkrieg with WW, and EFHW with Dylan for 5 RCWP. Alternately you can swap me with Dylan for 5 RCWP if I am blue. So Dylan works N2.
If either of [Jake, Chairs] is mafia and mafia is yellow, then only the other of [Jake, Chairs] is correct in his spot and we can only get to 6 RCRP.
So N1 and N2 together both seem to implicate Dylan as yellow and mafia, and clear EFHW, Jake and Chairs as town.
N3:
Yellow: Galz
Blue: WW, Iguana, Jake
Red: Haddock, e, silver, EFHW, gkrieg, Awaclus, Swan, Dylan, chairs
Right colour right place: 7
Right colour wrong place: 3
Gauranteed incorrect: Galz, WW
Guaranteed correct: Haddock, e, silver, Swan -- So we need three more.
Maybe the solution is that I am blue, WW was framed yellow, and Dylan is yellow. Let me check that.
RCRP: Iguana, Haddock, e, silver, EFHW, Swan, chairs
RCWP: Gkrieg, Galz, Jake (swaps with Dylan or Awaclus).
That actually works.
N4:
Red - Dylan, 2.7, EFHW, Haddock, chairs
Yellow - Jake, Iguana
Response:
Right colour right place 5
Right colour wrong place 1
So on N4, if I am blue, Dylan is yellow, and Jake has been framed yellow:
RCRP: Jake, 2.7, EFHW, Haddock, Chairs
RCWP: Dylan
So I at least have a theory that explains the results of all nights, where Dylan framed WW on N3 and Jake on N4.
