Problem with insurgence (mac)

Basically I was playing insurgence and one day i saved and turned it off and came back and the save file I was playing on was completely wiped of my playthrough but the other two were not wiped so I looked at my save files and the one I was playing was suddenly gone so I used the backups but they didn’t work, what should I do (plz help I just beat gym 2)…

Did you rename the saves to Game.rxdata?

Yes I have

yo…hold up…if i download it for the first time on the website, do I need version 1.2? or will it automatically just do it? and anything else i should other than unzipping it after it downloads? BTW its on mac

You won’t need to get anything else if you download the core instead of the patch.

thanx (:
