Replaced Custom World Save File
I was making a custom world star system save and when the world was saved I got the message stating something on the lines of; "Ran out of memory, could not save." So I exited the world and on the title screen was "Resume Game: Star System" I clicked on it and it loaded to a basic star system with no customization and no mods. I saved and quit and went to custom worlds and it showed what I did in that world. Is there any way I can fix this?
Edit: I found the custom world file. Can anyone point me to a unglitched star system file I can download?
