How do i fix a corrupted file on fallout new vegas

Unless you're a binary editing guru, there is no way to fix a corrupted save. You will need to load an earlier save. If other saves display the same problem, roll back any changes you've done to your mods or try a fresh install without any mods.

There isn't much that can be done about the corrupted save. Just load from previous save, that usually worked for me.

I haven't figured it out 100% sure, but this seems to be related to Steam Cloud sync. To disable it, go to Properties, select tab Updates and untick checkbox for Enable Steam Cloud synchronization for ….

Another possibility is that it happens when you're making a save while previous save is still being written to disk. Disabling auto-saves and relying only on manual saves could help.

I can tell you, from experience, how to recover your manual save (not your auto-save). This has happened to me several times on xbox 360. Not sure what platform you're on, but probably will work for any.

The problem is with the auto-save. It gets corrupted and somehow affects your manual save's ability to load as well. So, you need to overwrite your auto-save.

To do this, start a new game and get to the point where the game writes its first auto-save; this is right after you wake up in the doc's house.

Then, load your manual save. You should be good to go.

Start a new game, then load your save game file. That worked for me.

Try loading your pervious save and THEN load your corrupted save (if autosave was corrupted then make sure you don't overwrite it). Worked with me.
