I’ve never used the saved game feature myself so I can’t help there. If you’re still stuck with the save system I’d suggest looking through the various saved game threads. There’s a couple of saved game systems out there. I think there was one bumped fairly recently that might be able to help. ChoiceScript Saving Plugin (Update: Sept. 2019)
If you’ve specific questions about the stats screen feel free to ask and I’m sure people will help out.
