Server notes
Aloft has no config files — all 9 parameters are passed via command line (create# to make a world, load# to load it). Installing the server requires a Steam account that owns the game — this is the biggest difference from most game servers. The server is a Windows binary; Linux must run it via Wine (Winetricks: mono vcrun2022 wmp11 mf required). Saves are under the Wine prefix in the Saves directory — always back up before deleting .wine. Stop the server with SIGINT (Ctrl+C); the ready signal in the log is Server Ready.
