The Marignon delay request may have been asked for so that the returning Marignon player (vfb) gets a chance to do his own turn rather than the one submitted by the sub (Toran). As I'm sure vfb would like the chance to ruin the chances of his own nation
It's also possible that the current Marignon turn is just a 'token' turn (just recruitment), and submitted to avoid a stale (just in case the delay request got missed/refused)
So I suggest that rather than everyone getting their turns in by the original deadline (so that the quickhost kicks-in), that the quickhost should be turned off to give vfb a chance to get a proper Marignon turn in, or until vfb confirms that he is ok with the quickhost being on (ie. He is happy with the current Marignon turn that has been submitted)
My own opinion is that regardless of whether or not a turn has already been submitted for a nation, if that nation asks for a delay, they should be given the chance to use it. The quickhost feature is not always a good thing IMO (and in fact I won't be using it in future games that I organise)
Edit: Having just checked the admin logs, the email for Marignon hasn't been changed back to vfb yet (which is to be expected given qm's timezone). So another good reason to turn the quickhost off for the moment.
