Factorio Forums

Tried to load this save I've been playing with for a few hundred hours and got an error message:
Could not load <path/filename>...Bad Zip File.
https://www.dropbox.com/s/oedn8e31bcxgb ... d.zip?dl=0
(couldn't attach it)

Normally would have just reloaded from a previous auto save, but I've been playing the supply missions unwittingly. So they've been overwritten.

Trawled around the forums etc but couldn't find anyone with the same error with a fix that helped.

Specs:
version 17.42
AMD FX4300
Windforce 970
16g ram
Gigabyte MA-970

Thanks and regards,

Thanks for the report however the zip file is corrupt and invalid. There's nothing that can be done to make it work.

Something outside of the game corrupted the zip file (bad RAM/bad Hard drive/some external program).
