I could not find any results newer than 4 years old; so hoping I can find new info here.

My power just went out; so I just lost progress to a game I was playing by myself with AI for two weeks (huge map).

Is there really no way to get that game back? I checked this link: https://www.warzone.com/singleplayer/savedgames, but there is nothing there.

Games automatically save using local storage on the device you started to play the game on. So either you’re using a different device or cleared storage.

Local storage meaning directly on my hard drive or RAM? Because if it's RAM and the power when out, then it'd be gone I guess. I am using the same device.

Don't delete cookies/cache. Whitelist Warzone in your in your options/settings. That should hold it.
If you want to delete cookies, uncheck Warzone, delete the rest.
