The theme split is going to be:
Tried to hide their autism (whether directly or indirectly) as the Town trait with Not known to have actively hidden autism as Mafia trait
This clearly has nothing to do with good vs evil, it's a themesplit to increase awareness of asperger's and autism. More autistic people, until very recently, were 'in the closet' than weren't. That is the reality of it and what I also want to highlight.
Being known for one's Autistic Specturm Disorder and hiding it in the time period before it was seriously known about has nothing to do with hiding the name, instead it has to do with masking well in society or not.
This is to allow there to be flexibility to Mafia to both get away with a real claim and choose to research well and pick a good fakeclaim.
Mafia will not be given a fake-claim pool as I predict a small player pool with what you claim being a large way to catch people out.
I will try my best to balance the setup well.
