Why does PotD FORCE you to queue in-progress?

[aesteval]

Common sense? Even while it technically isn't the DF per se (well actually from a coding standpoint it probably still is), literally EVERY other duty in the game makes you start at the beginning, UNLESS you happen to have left the "join party in progress" box checked by accident.

...nooo...common sense would spring from intuitive UI design. Someone was lazy here.
