Why your Mermaid Isle 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.
