There is only one real problem with that method if using GWX or any mod that includes the lit ships
If you use it and leave the class name blank then any ship of that type= in the named countries roster will appear
IE
[RndGroup 80]
GroupName=HX40Convoy
Category=0
CommandEntry=0
Long=-7619130.000000
Lat=5344140.000000
Height=0.000000
DelayMin=60
DelayMinInterv=10080
SpawnProbability=90
RandStartRadius=0.000000
ReportPosMin=720
ReportPosProbability=60
Heading=138.606003
Speed=8.000000
ColumnsNo=6
Spacing=1000
DeleteOnLastWaypoint=true
CurrentInstanceID=0
GameEntryDate=19400104
< note the date
GameEntryTime=240
GameExitDate=19401226
GameExitTime=0
NextWP=0
[RndGroup 80.RndUnit 1]
Class=KSS
< Small merchant will spawn
Type=102
Origin=Norway
Side=0
CargoExt=3
CargoInt=1
CfgDate=19390801
No=1
Escort=false
SpawnProbability=50
CrewRating=3
[RndGroup 80.RndUnit 2]
Class=NCVW
< Whaler will spawn
Type=101
Origin=Norway
Side=0
CargoExt=5
CargoInt=0
CfgDate=19390801
No=1
Escort=false
SpawnProbability=50
CrewRating=3
[RndGroup 80.RndUnit 8]
< No class name so any type=102 in Br roster can show
Type=102
Origin=British
Side=0
CargoExt=1
CargoInt=0
CfgDate=19390801
No=2
Escort=false
SpawnProbability=100
CrewRating=3
Now if you remove the class name the game has a choice of any ship of that type= from Norways roster
[RndGroup 80.RndUnit 1]
Class= (
C3Cargo\KBL\KCA\KLS\KSS\KSQ\KGN\LLS\LSQ\LSs )
Type=102
Origin=Norway
Side=0
CargoExt=3
CargoInt=1
CfgDate=19390801
No=1
Escort=false
SpawnProbability=50
CrewRating=3
[RndGroup 80.RndUnit 2]
Class=
( NCVW\OTMS\OTSF\OTSFT2\NECT\
LTMS\LTSF )
Type=101
Origin=Norway
Side=0
CargoExt=5
CargoInt=0
CfgDate=19390801
No=1
Escort=false
SpawnProbability=50
CrewRating=3
now as said earlier note that convoys date 19400104
At that date Norway is still neutral and as such all above classes in
blue are still available to be picked from the roster
The ships are lit
So you can end up with lit ships in a convoy
After Norways date of occupation those ship classes in
blue are unavailable to the Norway roster so any convoy entry can be generic ie no class names as the only ships left are the
yellow classes which arent lit
Here endeth the first lesson
