[1.0.0] game.auto_save fails to save to subdirectory

[Shados]

It is possible to save to a subdirectory when using the save menu (although the subdirectory must first be created externally), which is useful for organising and grouping game saves. `game.server_save` is also capable of saving to subdirectories, but `game.auto_save` fails to do so.

I believe the issue is related to `game.auto_save` adding a `_autosave` prefix to the save name, as it does successfully create a subdirectory (with the `_autosave` prefix) but then attempts to write the save file into a nested subdirectory of that subdirectory (according to the error message and log file, which is attached to this post).

Thanks for the report however that function does not support saving to sub directories. It specifically asks for a name and that name will get put into the default saves folder.
