Also weirdly the client still thinks said commands are in it's completions, but the server doesn't recognize them.

To reproduce:

A dedicated server with some custom commands and connect.

Execute a command which was added

execute /reload

try to execute the same command again.

Tests do not fail here since the tests only run when server has first started.

Hmm, previously commands are all registered before a server is created. Wonder how the recent command changes worked.
