I have no idea. I never played for trophies in V3, but I may go back some day. It might be a glitch but I couldn’t tell you.

It's alright. I may replay it soon. I know that except for the casino I try to get all are already have them. I have so far Platinum on all Danganronpa games except V3.

I'm having troubles with trophies in other games, i never got one in Automata aswell as i had to redo a thing in Undertale to get it. I should check if other people had the same problem recently, because if that's the case it could be over the fact that Sony is trying to implement name change on PSN which gave beta testers problems with DLCs and trophies

My problem is since the game came out. But i agree, i hope they fix this.
