Hi there!
I made this mod because I was fairly unsatisfied with the secret scene for completing the Pokedex.
Mod description: This mod changes the 100% Pokedex completion scene behind the door in the Citrae Astrae to better respect player agency in cases where Lin was not saved. If you're curious about the exact change and exactly why I made it, open the spoiler below.
Installation: Copy the attached file into the game's Data folder. It should be compatible with any other mod that does not edit the same file.
