You know what, we're all reasonable people. I'll show you my problem and let you help me decide:

As you can see, the HML Courser's sudden deceleration caught the Chasse by surprise, and he overshot, but also overlapped.
By my guidelines, the Courser should be moved back, because it's the ship further back in the overlap. However, even backing Courser up by the entirity of her move leaves the overlap in place.
The only other option is to back up the Chasse, but to get the Chasse into a position where there's no overlap requires going back 3 hexes and 4 MP, fully half of the move. The net result is that Chasse gets the advantageous positions which, no offence to Lord Cameron, I don't think is right this turn.
Do either of you (or anyone else) have a suggestion? Is there a rule for stacking in the more advanced rules. Are you happy to play on?
