Before, they were being saved to an SH4 folder in C: Documents and now they are being saved to an SH4 folder in C but not to Documents. I am playing the Ubi (uplayer?) version.

If anyone else comes across this vanishing saves issue, the solution is to copy the SH4 folder in C: Documents to C. The game will then 'see' them

just a bunch of quick thoughts:
are you running a system optimizer?
does your antivirus run a system optimizer?
by chance, could someone on your computer have accidently dragged-and-dropped a higher-level folder out of its normal folder? (i've done that accidently)

great to hear that you were able to recover.

to answer your original question, no, i've never heard of this happening.
