MJ2 won't launch into the plane of my target

[maddog59]

I have a target craft orbiting Kerbin East to West (rather than the usual West to East) and need to get another ship up to it. When I use the 'launch to target plane' function, then engage the autopilot, the game warps to the launch time, the engines activate and the throttle goes to 100%, but the vehicle doesn't leave the pad - no flames, no noise, nothing. It just sits there. MJ2 shows that it's 'launching to target plane' but nothing is happening.

MJ2 works properly for the other launch options. Is this a bug? Or is there something about using this option that's different from the others?

Disregard ... the problem is that there's no probe control.

If your craft lacks a control core and the engines are on, it will simply be unguided (perhaps a TWR problem as-well
