Using saves from an older game version in a new game version

[GeeSeki]

I know it might be pretty hard but does anyone have a solution to this issue? My game is in development and I release an updated version every few weeks. But everytime I do that, the old save file becomes useless in the newer version because it'll cause errors such as variables not being defined. Is there any solution to this problem? The only thing I can think of is to implement some sort of feature that resets a certain part of the game or at least set all the variables to its first state.

possible solution

Delete the "cache" folder in your game and also the "saves" folder

Variables not defined error is happen because you haven't defined variable as default during "init" period. Here is the link to documentation on "default": https://www.renpy.org/doc/html/python.h ... -statement
