They should just use the average time of the five review plays--making you start from scratch once getting out of review isn't reasonable. Even if you get 5 people to spend 3 hours AFKing on it during review (which is highly unlikely) it's still only 5 reviews and the average play time will drop as soon as other people start running it. There is no good reason to keep doing it this way with the removal of the wrapper mission.
The red Message besides not work properly, I have two missions that meet the requirements and are in red should be removed, if Cryptic to put a progressive reward system should remove all red messages that are preventing good missions not played for his fault.
And if they will not remove it unless you tell the author as a "fix" for not staying with hours of work without reward. At least for me, is that people play around I created missions.
