It may be ok, best thing to do would be to try.
for prevention, turn off all auto save options, don't use quick saves and keep as many different saves as you can, best to make a fresh save than overwrite an old one.
Saving while taking damage is another thing that is known to cause corruption, such as vampire sun damage or a duration spell. I personally never save while there is any active effect with a timer on my character.
Ah, that's it, I went to bed and woke up as the "level 2 vampire", I went out to find that I take damage from the sun, I saved, went to find out how do I cure myself, tried loading back and the file was corrupt.
I had a save which was done only 15 minutes before the corrupt save, which works, so yay! I'll turn autosave off now.
Thanks for the help! Appreciated.
