Describe the bug
it's happen when i try to shotdown my server

To Reproduce
just intall the snapshot 569 and shotdown your server

Expected behavior
expect no errors on shotdown

Screenshots

Version Info
snapshot - build 569

okay no problem igoring it
but the server is empty and whitelisted

This seems to be a case where a player connects while the server is shutting down, but the channel was injected before - I would say that you can ignore that, there is not much we can do to prevent this from happening :/
