Is there a way to save a map without also exiting it?
In Terraria 1.0.4 devs added an auto save option:
- Added an option to automatically save the world every 10 minutes. Defaults to on.
I usually use a server to save my world without exiting the game. Even if I'm playing in single player.
I create a server with my world before I start playing, then, when I need to save the world, I type "save" in the server's cmd window.
The server also autosaves the world at regular intervals.
