GPU stays connected after pushback with APU off

[NeoZoan]

This is more of an error in procedures on my part, but I think the consequences need Polish. I neglected to turn on the APU before pushback and there was no ill effect. Other aircraft I've used will penalize you for this by abruptly disconnecting the GPU. The external model also still shows the GPU attached even dozens of feet away from the gate. I would not expect this to be high in your list for fixes, but wanted to point it out.
