1) when you have a zipped version and an unzipped version/folder you dont know which is which inside the load gui.
eg. /saves/mygame > "mygame" and /saves/mygame.zip > "mygame"
my solution: add the .zip extension when both are present.
eg. /saves/mygame > "mygame" and /saves/mygame.zip > "mygame.zip"

2) when you have a zipped version and an unzipped version/folder you can't save that game.
error:

There are multiple packages for package sl-extended sample map in directory /home/sl/.factorio/saves (mygame.zip, mygame)

my solution: ignore the folder version and just overwrite the .zip version.

Well, you are supposed to use the zipped version of the save. If, for any reason you unzipped it manually, you should put it back as zipped. The fact that the unzipped version of save works is there only for our debug reason, and is not fully supported.
