Why codes might not work

  • The code has expired or was limited-time only.
  • Typos or extra spaces — codes are case-sensitive; copy and paste to avoid errors.
  • You already redeemed the code on this account.
  • The server or client needs a refresh — rejoin or restart the game, then try again.
