I have stopped playing for a couple of days. Now i want continue playing Wasteland 3. But there wasn't any save game any more. I already played for 30h. I downloaded the save game file from the cloud, but it's empty. There no local files, too.

One of the patches moved the saved games around on the pc. I don't remember where they were moved to, but they should still be on your system somewhere.

What's weird is when it does this, the cloud save shows as not being valid, but it should be a matter of tracking down that info (Might be in ~appdata) and copying it to the new saved game folder.

Good luck, I know this isn't much but maybe it'll help.

Thanks!
Now I have found them. It seems that the problem was that I have Wasteland 3 not installed on the C drive. I found them on F:\My Games\Wasteland3\Save Games

You're welcome :D Glad I could be of help. Have a great evening!
