Late-Joining traitor too late

[BlackPhoenix]

Hi, if it's possible, it should be made to where you can't become a latejoin traitor after the shuttle arrival timer is below 5 minutes and beyond. At that point, you don't have time to do anything interesting, and it definitely won't be recalled so there's no harm in not being able to become a traitor. It'll lead to much less disappointment and sadness.
