ernyoka1, Skip the details, for now, on what it does and why ;-) Put it this way, when you first bought V3 and encountered the Injection system, you probably assumed that everything else would work as before. Only later did you discover/hear that only the first figure loaded could accept injections. Try injecting any subsequent figure in the scene, and you got crosstalk-like symptoms. Generate the FII bank, switch to it, and then Mil3 Injection figures will work like you originally expected them to. Simple as that!
