so I'm stuck in the endless credits and that made my last trophy glitch, which means no platinum that I should have had a week ago. I was waiting for a patch to fix it but we all know how that went.

My question is if anyone knows if I can get the trophy from doing the "hidden" ending in the beginning or if it only pops from the last story mission only.

Basically can I just start a new game and do it now or do I have to continue waiting?
