Hi, could you give me a list with the mods you've installed?

I did push a fix that defaults a planet's scale to 1, if no surface properties are defined. But I do still like to see which mod is causing the error.

400 active mods :|

Could you go to the mod folder:
Windows: %appdata%\Factorio\mods
Mac: ~/Library/Application Support/factorio/mods
Linux: ~/.factorio/mods

open the "mod-list.json" file in a text editor and copy paste its content to here?

Thanks! There were three mods (Undersea data cable, Thruster control behavior and Space platform graveyard) that defined "planets" without surface properties. This is entirely valid though, so I've fixed it on my end. Let me know if you encounter any other problems.
