After completing an expedition, my Steam client crashed completely, leading to the GTFO executable crashing as well. Upon restarting Steam, the game still showed as running, but the application didn't recover. After relaunching GTFO, the expedition I had just completed (R5B1 Prisoner Efficiency) was marked as incomplete.
This is the second time this has happened to me (first time was on R6BX).
Is it possible to "reinstate" the lost progress? Moreover, I would love to find a solution to prevent this fatal error from recurring.
