I tried everything you mention but still nothing there is always just my first mission when i go to continue. and no other slots in Load game :/

I tried and still nothing. I have RUNE version. I try to copy it but when i go in the game it's still first mission to find the watchtower what i did. :/

96ad091fce494a94ad201d02d4413ef5 - put it in C:\Users\Username\Documents\My Games\SnowRunner\base\storage with replacement
Or
base - put it in C:\Users\Username\Documents\My Games\SnowRunner
In theory, both options will be correct.In the first case, there will be a save with your settings saved. In the second case there will be all author settings.

try this too
SnowRunner: SaveGame (all locations are opened) [30.0]

Try it now. Now the whole folder

I did fresh install because i lost my save game. But don't know how to make it work with your files. I just copy in Documents/My Games/Snowrunner/Base or? Whatever save i use from this site it won't work it always show first level with truck starting when i go to continue
