I have an issue with one of the achievements for the game, "So Many Me." In the game, there is an achievement called "Cosplay Champion," where I would have to acquire all 42 costumes.
However, I did unlock all the costumes. I have all 42 costumes unlocked and I can switch to each one with no issue. In the achievement tracker, it shows that I'm at 85%. I know that I can probably attempt at the achievement again, but for this achievement, I cannot go back on my save file. I have already purchased and acquired all available costumes. Also, in my achievement list, there is another achievement called "Impossible," where I have to reach 100% completion on the game.
So my question is that how did I complete 100% of the game, but the costumes didn't register properly? I couldn't unlock the achievement for "Cosplay Champion." I can provide photo proof that I have acquired all 42 costumes. Is there any way to get this achievement unlocked without deleting my game save and starting from scratch?
