Editing your save variables is the last thing to do. The more playthroughs you do, the more entertaining your game process is. Fairplay only.
But removing a 4 points penalty for Week3_TC_Cheer_Late on Valeria's path in Ep. 10 from the script is what I'd recommend to do since that's been done already in Ep. 8, and that's weird to be done again for it to become a double penalty now, I guess (What's Nyx's point here?). Just my advice as an option for preventing you from losing Val on Gabi's or Tori's paths in Ep. 10 due to this bug (???).
