Is it normal that this code return NULL on behaviourGroupInfectedPack? (script in 4_world)
AIGroup m_AIGroup = GetGame().GetWorld().GetAIWorld().CreateGroup( "MyIaGroup" ); //=> ok AI group is created BehaviourGroupInfectedPack behaviourGroupInfectedPack; Class.CastTo( behaviourGroupInfectedPack, m_AIGroup.GetBehaviour() ); //=> behaviourGroupInfectedPack=NULL
