Difficulty trophy glitch

[Eyes_Grim]

I can confirm the glitch still exists.

I was able to unlock the collectibles trophy, but for some reason the game wouldn't count the last battle in hard mode  and crazy mode as completed.

Luckily I am a backup save file maniac so when I returned the save file before the last battle and re-attempted it I was able to unlock the difficulty trophies on hard and Crazy.

Keep backing up your save files before each battle if you want to save your sanity or else you will have to start anew, I am afraid.
