My previous firing attempts are invalid because the time “must be a time of the pilot’s choice between 18 and 72 hours after the time at which the comment is made”. Accordingly:

Of course, that firing comment is still only valid if the Bogey is actually a Bogey, which I’m not sure of. The Emerging process is confusing.

The Bogey should be a Bogey - once it has emerged it becomes a Bogey, right?

Was my order invalid?

Ah, yes it was - sorry. It needed an 18 hour gap and gave just under 12.
