Always same crew characters...

[Hitman]

The crew will use body % head at random in the stock crew rosters, apparently Ducimus -if this is normal in TM, that is- cloned the crew and forgot to add some variation to them?

The crew definition file is -I think, never tested it- located at: Silent Hunter 4\Data\UPCData\UPCCrewData\Crewmembers.cfg

Inside it you can find the definition of all parameters for crewmembers, for example:

[CrewMember 1]
ID= NR
NameDisplayable= John Brunner
CrewMemberNameIDLinks= NormalUSNames,CommonUSNames
DateOfBirth= 1920-11-05
Head= 2 ; model of head used
Voice= 2 ; voice used
Tatoo= 1 ; wether is has a tatooo or not
Rank= NR3rdClass
CurrentExperience= 0
Qualifications= NULL
SpecialAbilities= NULL
IntelligenceCoef= 0.5
LeadershipCoef= 0.15
MechanicalCoef= 0.3
ElectricsCoef= 0.3
GunsCoef= 0.3
WatchmanCoef= 0.3
Medals=
Patrols=0
Morale= Normal
FatigueCoef=0
Hitpoints= 5
RenownCost= 0

If you open your file and all crewmen have the same line, then you can simply randomize them a bit and you'll get more variation.
