Factorio Forums

Hi, I play Factorio everyday and last played it yesterday and everything was fine. Load the game up today and im no longer logged in and have to log in and also when trying to load my save I get an error with this:

Opening zip C:/Users/Administrator/AppData/Roaming/Factorio/saves/lets try 2.zip failed: Bad zip file

Not come across this before and certainly never had to re-sign in as well.

The file is corrupted and cannot be repaired, this can have multiple causes like a drive failure or an error while saving.

so I've lost all them hours of work? So how can I prevent this from happening again?

What would be the explanation for having to re-sign in then, as this has never happened before.

The fact that you had to login again suggest that other files got corrupted as well so I'd check for a drive failure or an anti virus software that interrupts factorio while writing to files.

Ah I see, maybe time for a new drive or whole new computer then. Thanks for your help
