Crushing trophy won't unlock because of problem with stage 7
I beat every stage on crushing difficulty and didn't get the trophy. When I looked at chapter select chapter 7 said that I beat it on moderate but I know that I didn't I beat it on crushing. So I've went back and I've beat it 4 times now on crushing and when I was playing it I checked at least 12 or more times to make sure that it still was on crushing and after I beat the chapter again still nothing. I ran the finale again a couple of times after I beat because I saw were someone said that how they got it but still no luck for me. I have every trophy already but that 1 and the platinum and I didn't know what to do but I'm getting sick and tired of this game really quick and don't think I should have to beat the game 10 or 15 times just to get all the trophies when they should unlock the 1st time.
Can you please help me with this problem because I still can't get the trophy to drop on crushing mode. Every time I beat level 7 it still has moderate on it even though I beat it on crushing and I need that trophy to get the platinum one.
