a minor bug in /challenge

[omareco14]

when typing an unknown command or any other command in /challenge it says "type /kill to exit this activity"
/kill actually doesn't exit it, /leave does

It is just a spelling mistake, and spelling mistakes are reported Here.
A player has already reported it.

Today while playing this challenge i found this bug...So as u can see in the photo down it tells u that u have to type /kill in order to exit from this activity .but that's not true cuz when u type /kill u just die and then gets respawned into the challenge area again .It must be "sorry u must type /leave to exit from this activity".
