Previously saved locations turning red.

[Lizard of Oz]

I have been saving my favourite templates in User 1-3 locations and numerous times now after the save operation the 'load' button greys out and the location lettering turns red indicating that it is empty despite me just having saved there and many times previous to that. Ì have started saving the same setup in all 3 locations now just in case and once it lost all 3 before I realised the significance of the red lettering. Fw 1.1.035

I had the exact same issue on 1.1.052 yesterday, two presets turned red after saving. When I checked the SD card on my mac, I saw that the preset files 002.INI and 003.INI were gone, but the IPLUT and OPLUT files for that preset were still there. I then duplicated the 001.INI (the other two were copies anyway) and popped the card back in, and everything works fine again.

To me it was not obvious that the save operation had failed, it took me 2 times to notice that. I think after a save operation the system should test if the file exists, and show a warning to the user if it doesn't to prevent the user from losing data,

It appears that users have to rely on removing the card for making backups, because there is no other way of getting the data out, so even if the root cause is a SD card that is not correctly inserted, maybe the system can take some steps to prevent data loss? Like making a copy an old preset before writing the new version, so it can be verified that writing files is possible? That way, the system could show a warning before saved data is lost.
