I played for almost 7h30' and saved twice in slots n. 18 and 19 before copying the patch files over my folder, both being version 0.80 but I got stuck at the bug of a black screen. However now there is no trace of my saved files, there are just saved logs between the 20th and the 34th slot, but my past 7 hours of gametime are completely gone. Is there a way to get them back or get to the same point in the story?
