Lost Progress

[jompa55]

Lost my progress in the game because I somehow uninstalled my game. Is there anyway for me to gain it back? I was on the map where you lift a sword. Lost about 12 hours of progress . Steam below.

The game doesn't save your progress on the cloud, but you can manually edit the "CompletedLevels.txt" in the Besiege_Data folder (it's the folder 1 above SavedMachines).

This has to be done while the game is closed.
