When you try to save the
game, Kaspersky has deleted the file ashore.exe and issued a message
about the detection of the virus - PDM: Trojan.Win32.Generic
Of course, I just downloaded it yesterday from https://ashore.itch.io. This does not always happen. I checked that there are really no viruses, but it happens to be triggered by Kaspersky and it deletes the file.
Sorry for my english
