Save game when patching (or anything useful)

Hi,

I have a question about save files and what happens when patching your project. Recently I had some issues with a save file not loading correctly when I packaged my project to a shipping build and tried to run it. Later I found out that it was because of an older save file with the same name saved at the default save location for save files in shipping build (users/user/appdata/local/projectname/saved/savegames). When I deleted those and let the program itself create new ones, the problem was fixed but of course the variables were reset to default.

So I was wondering what would happen to the save files when creating a patch for the project? Will the save files still work as normal? Will it automatically revert to the default values? Will the files need to be manually deleted so the system can create the proper new ones?

Basically anything I need to know about save files in a shipping/production environment is welcome!

Thanks!
