I've been made aware that updating my Unity game on the website causes the save file location to move to a new location. My game uses Application.persistentdata path to find a place to save a json file, but how can I update without the location changing? Are playerprefs what Unity games need to use to save their games without being lost?
I know you can avoid the issue if you use File (which will point to a place in IndexedDB which you can specify as a parameter to its functions) and hard code a path to something like yourName_yourGamesName so it doesn't change when you push an update to your game.
It might be better to see how I did it than try to explain -- this was a sorta slick thing I did when I assumed that most newbies would use PlayerPrefs (like I did in my first game) and get burned by it because it suffers from the same problem you're facing. I basically wrote a script to override Unity's PlayerPrefs behavior and make it write to a location you want. Here's the source code, and the class constructor and Save() function are probably what you want to pay attention to.
