I had given up on the platinum...and haven't played it since. I have read it has been fixed, and am going to fire it up soon. Hopefully it works. As for your issue prince, only thing I can think of is starting a new game.

It's been a year...but I seem to remember that trophy popping while doing the campaign. However..the Endeavor/Evolution trophy is still glitched for me. Hopefully you have better luck with the 100% then I did.

I have the updated patch...and I played through the game a second time. The trophy Endeavor / Evolution and the platinum still won't unlock.
