Why your Build An Island codes are not working

  • Typos. Use the copy button rather than retyping — one wrong character is enough to fail.
  • Capital letters count. Most codes are case sensitive, and a trailing space breaks them too.
  • It expired. Anything in the archive below is dead for good — no amount of retrying brings it back.
  • Fresh code, old server. A brand new code sometimes needs a server restart. Leave, rejoin and try again.
