This mod simply edits MQ206 (molecular level) to make the following aliases optional

DoctorAmari
Virgil
Desdemona
TinkerTom
PAM
PrestonGarvey
Sturges
Danse
ElderMaxson
ProctorIngram

Even though flagged to allow dead the game will actually remove them at some point when they are dead and the quest will fail to start because without the optional flag on an alias the alias must be filled before the quest can start.
