You might be right but Flower never really lied about indie wincons so I tend to believe her but if she does now she basically burns that bridge.
Same thing I think of with Miller claims
If someone is known for tellin the truth about a certain element then they put their reputation on the line if they lie about it. A single win in a game is not worth never being trusted in that regard again.
Flowa claimed neutral, has helped us with set-up info that has shown accurate so far and has even killed one of the mafia that led us to getting rid of a cult leader early on
I'd say it's fine to roll with it for now, and we know who Flowa is as well so it's not like we're running blind here.
