[1.0.0] Bad zip file after migrating 0.17 to 1.0

[CombustibleToast]

Hello, I was playing yesterday to check out spidertron and all was well. I did have a few hard drive issues while playing, but it was on a different drive than the installation of Factorio and its saves (E: was having issues, Factorio is installed on D: and saves are on C:). Today when I go to open Factorio, it was uninstalled. After I reinstalled it and tried to open my save, I get the notice saying it's a bad zip file. It, along with its autosaves, are all corrupted in the same way. I've attached all four saves and the factorio-current and factorio-previous logs. Is there any way I can get my saves back? Steam has also automatically uploaded the corrupted saves so I can't retrieve them that way.

"Bad zip file" sadly means that those files are unrecoverable. If all of your save files are corrupted I would strongly suspect a drive issue on the drive they are stored on.
