Keep in mind, a lot of things could happen to cut scum off - Envy could hit the Radiation delayed roleblock, get lynched d1, get blocked, get bussed or redirected so he replaces a TEAMMATE (I'll admit, I was really hoping that would happen) or attempts to replace himself.
Between:
Cheeetar's Sleeping Mod (har har) powers
RedWarrior0 as a survivor who has a one-shot kill-immunity and investigates his killer
Neruz the redirector
SHAD0Wdump the busser
Bayer the Nuclear Rocket Surgeon
Mr.Person being able to investigate (possibly exposing Mafia to gain credibility before dropping a lynch on his target, Eduren)
Meph having the ability to clear Dak and disrupt scum's vigclaims with day-forensics
Dak having a one-shot daykill (even with it's chance of random redirection it could technically by randomed to the same person or another scum, or even to scum if he targeted town)
Apostolic Nihilist with his crazy JOAT-Evolution power (and even being able to draw Poisoner)
Toony's roleblocks
Webadict's Supercop powers (you should've lynched Org for blocking him repeatedly, you know)
Eduren's pardons
The awful things Zai could do if you hadn't lynched him so soon
Rashilul's RTD player craziness (including his ability to sane-investigate and role-investigate his hammerer or killer without even dying on a 5 role)
ExKirby's medium-powers
Org being scum and having everyone told what he does (you should've lynched him for blocking Webadict repeatedly, you know)
Pretty much every player had a way they could fuck the scum up, even if they were neutral. Most of them just didn't.
It was theoretically possible for the scum to lose d2 with no townies dead, though not with Jester/Lyncher victory. I can explain it if you don't believe me.
