Oh good idea - the default save data system is very simple on purpose - it's designed to be integrated into other systems for anything more complex. (I'm working on a versatile save data system that'll integrate into fleece right now)That said, I should add a method to that class so values can be reset quickly...
The visited array already has a reset function that's called in the sample scenes, so I'll add a base reset function to parsers that can be called at a similar time... outside of the sample scenes, just like with the visited array, it'll be up to the developer to call it at an appropriate time - but I'll add a button to the default parser so it can be done though the editor.
It might take a bit longer, but I'll make sure to upgrade the save data system soon! Should I email you a build to test it out when I've got it working?
