Here is video proof of this strange phenomena happening live:
twitch.tv/swordofseals/v/52825041?t=05h05m35s
Scenario:
Voting Screen
3 players left
2 players joining (1 player tried again after kick)
Problem:
Players can apparently join the room during the voting screen.
(This is similar to how Mario Kart 8 Day One DCs worked before Nintendo applied the server fix)
Symptoms:
Watch the voter count in the bottom right flicker as players enter and leave the voting screen.
Fixes:
Joining players are listed as "guests" on the Wiimmfi page.
Kicked 2 players while they were joining inside of the voting screen.
1 player tries re-entering the room while the voter count is stabilizing. Kicked 1 player again.
Room count is restored to a sane value. Game confirms that this is correct and proceeds as normal.
