Why your Build a base RNG 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.
