problem with spectator

[Kenix]

When a player dies and goes to spectator can't spectate to another player .For example 2 players alive ( players in spectator can spectate players ( who get "Status" == "Playing" ) ), but sometimes when you switch the button( on keyboard ) "arrows" does not work to switch to another player but he is alive and have is in the table alivePlayers .

Help guys.
