Yeah, I figured since an empire doesn't 'own' a star that the mechanism for selecting a target wouldn't work for that one. Phew...
Here's my "Biological Warfare' project:
Name := Biological Warfare I
Description := Deliberate infection of a planet with level 1 plague.
Group := Planet Sabotage
Cost := 50000
Type := Planet - Plague
Effect Amount := 1
Num Source Messages := 1
Source Message 1 := Our operatives have covertly spread level 1 plague on planet [%PlanetName] in the [%TargetEmpireName].
Num Target Messages := 1
Target Message Title 1 := Plague
Target Message 1 := A plague has broken out on [%PlanetName]. The people are crying out for a cure!
Source Picture := IntelSabotageByUs
Target Picture := PlagueBreaksOut
Number of Tech Req := 2
Tech Area Req 1 := Sabotage Techniques
Tech Level Req 1 := 3
Tech Area Req 2 := Biological Weapons
Tech Level Req 2 := 1
I'd still like to see MM allow us to select our own ships and planets as intel targets so we can counter-act mutinies and rebellions with our own intel projects.
