!!! ATTENTION !!!

You have /opt/valheim_dl mounted or old server files in /opt/valheim.

The /opt/valheim_dl volume is no longer required and has been unified under
    /opt/valheim

Directories have been moved in the following way:
    /opt/valheim/    -> /opt/valheim/server/
    /opt/valheim_dl/ -> /opt/valheim/dl/server/

You might want to (re)move existing files or create a fresh volume mount under /opt/valheim to clean things up.

Nothing is going to break though if you don't. It will just consume some extra disk space.
If required we'll download a fresh copy of the server in the new directory structure.

!!! ATTENTION !!!
