Icarus ResumeProspect does not work as expected

[jafnhaar]

My config file looks like this:

SessionName=Icarus1
MaxPlayers=8
JoinPassword=123123
AdminPassword=123123
ShutdownIfNotJoinedFor=300.000000
ShutdownIfEmptyFor=60.000000
AllowNonAdminsToLaunchProspects=True
AllowNonAdminsToDeleteProspects=False
ResumeProspect=True
LoadProspect=Icarus1
CreateProspect=
LastProspectName=Icarus1
FiberFoliageRespawn=True
LargeStonesRespawn=True

So according to this config server should resume the last prospect after server shutdown due to inactivity but every time I login I see prospect selection screen. What am I doing wrong?
