Epic Games Version Will Not Save

[malyzar]

I'm attempting to play the Epic Games version of SOMA, but the game will not save. I've followed the instructions posted here, to no avail. I've also checked both the My Games and Local App Data folders, but the game doesn't appear to be creating any save files whatsoever. 

Any advice? I've found several forum posts regarding this issue on the Steam version, but I haven't been able to find any solutions for the Epic Games version. So, I'm posting here as a last resort. Thanks in advance for any help!
