After updating to 0.8, existing saves are no longer recognized with a ‘no saves found’ message on the title screen load menu.
However, examining the Documents > My Games > Farthest Frontier > Saves folder, all files are still present.
When creating a new game and saving it, this save file is retained after closing out and restarting the game, but is not located in the same folder as the rest of the legacy saves…
Based on all the issues people have had with OneDrive misplacing, relocating, and in some cases losing their saves, I’d generally recommend not using it for frontier saves.
