5# Fallout New Vegas Quick/Auto Saves Fix
If you save your progress using autosave/quicksave, the game may revert you back to first quicksave when you restart the game, resulting in loss of all the game progress. Steam cloud may be the problem as there is no fix yet, and disabling steam cloud would disable the achievements.
Though, Steam has come out themselves to disable the Steam cloud for this game, and they are investigating these issues. Meanwhile, use the ESC/Save to save the game manually then using quick save hotkey to save instantly and save a lot. When you start the game again, you may notice that continue starts the game from the quick save so better load the game.

You can speed up the save process by using the console key to save the game. Here’s how:

  • Hit the ~ key.
  • Type save “save_mission or zone” and hit enter.
  • When you need to save the game, press ~ console key and press up arrow to get the previous save name, you can either overwrite this save or rename the save file for a different mission or zone.
  • Now when you need to load your saved game, hit the ~ key and type in load “save_mission or zone”.

How to Recover Your Saved Progress/Saves in Fallout New Vegas
via Steam Forums

  • Locate the save files folder, My Documents\My Games\FalloutNV\Saves.
  • Find files that have a *.bak extension. Rename the files with a .bak extension some other extension like .txt for simplicity. Now rename these files as old .bak extensions. Now try quick saving, hopefully it won’t revert back to previous saves.
  • If you don’t have any saves in there, try:
  • Navigate to your Fallout.ini in the FalloutNV folder and un-check Read-Only.
  • Open the file and search for “SLocalSavePath”.
  • In the SlocalSavePath= make sure the folder exists. If it isn’t, create the folder with the same name in the specified path.
  • Now, change “iSaveGameBackupCount=1” to “iSaveGameBackupCount=0”.

Update. Quick Patch has been released for the game, make sure you have the game updated.
