[2020] no cloud saves

Could you let me know if you bought CK3 on Steam, PDX Store or via the Gamepass?
It will help me so I can support you better.

To access and load all Steam CK3 cloud saves made or synchorinzed on given device you need to:
1. Locate and open folder "C:\Program Files (x86)\Steam\userdata\[steam_id]\1158310\remote\save games" - if the Steam was installed in the default location.
2. Copy the save file you want into "C:\Users\[user_id]\Documents\Paradox Interactive\Crusader Kings III\save games".
You are now able to load that save in the game as a local save.
