Not save files from the 'current version' of my game but save files from previous versions of my game. Players keep loading old save files even though I warn them not to and thus running into 'avoidable' bugs. It's frustrating. So I'm wondering if there's a way to just make it so that the old saves are gone or unloadable.
And more specifically, if it's possible. I would want to have save files loadable if the updates are minor (loading 0.19a save file in version 0.19c) but not when it's a major updates (loading 0.17a save file in version 0.19a).
How to prevent players from using old save files?

Re: How to prevent players from using old save files?
Some thoughts:
1. I'd prefer, as a user of your game, that my old saves could be used with new versions of the game. That can be done with the use of "default" for new variables. For more complex changes between versions, it can be done using the "label after_load" (I know that wasn't your question, just saying).
2. To answer your question, I'd use a variable inside the game to know what version that save has and check it in the after_load save:

3. More complex behavior is also possible:

Re: How to prevent players from using old save files?
Hey! Thanks for that! This is exactly what I need and it worked perfectly! I took your suggestion and made it a warning disclaimer instead stating that it's not suggested to use an old save file while allowing it to be used.
