"Type Mismatch" error - CK - Flame Atronach+PlayerChar

[Twycross448]

Folks, I wanted to play a forced sexscene between the playercharacter and a flame atronach.

 

My problem is that the Creation Kit always gives me a "Type Mismatch" error for the part where I declare the FA as an actor.

actor[] sexActors = new actor[2]
sexActors[0] = PlayerRef
sexActors[1] = Alias_Atronach

sslBaseAnimation[] anims
anims = SexLab.GetAnimationsByTag(2, "Doggystyle", "Aggressive")

SexLab.StartSex(sexActors, anims, victim=PlayerRef, allowBed=false)

As soon as I switch "sexActors[1] =" to another alias in the scene (there are 2 other NPCs, a female Nord and a male Redguard) the script compiles without error.

 

Is it actually possible to use Creatures in these scripts? Because the fact that it works with a normal NPC just fine and only throws the error once I put the Atronach in makes me think that way...
