Well, it looks like the Yor and Dread Lords are marked as active, but there's one part I'm not sure about. Here are the values for the 4 races in this mission:
[Human]
Human=0
Drengin=0
Altarian=9
Arcean=0
Torian=0
Yor=-1
Korx=0
Drath=0
Thalan=0
Iconian=0
Custom=0
Dreadlords=-1
[Altarian]
Human=9
Drengin=0
Altarian=0
Arcean=0
Torian=0
Yor=-1
Korx=0
Drath=0
Thalan=0
Iconian=0
Custom=0
Dreadlords=-1
[Yor]
Human=-1
Drengin=0
Altarian=-1
Arcean=0
Torian=0
Yor=0
Korx=0
Drath=0
Thalan=0
Iconian=0
Custom=0
Dreadlords=-1
[Dreadlords]
Human=-1
Drengin=0
Altarian=-1
Arcean=0
Torian=0
Yor=-1
Korx=0
Drath=0
Thalan=0
Iconian=0
Custom=0
Dreadlords=0
I'm guessing that the Dread Lords and Yor should be set to 9 like the Humans and Altarians? Also, common sense would tell me that the humans should be set as 9 under humans and same for the Altarians. Or is this all this way because I've already "won" the scenario?
