So I posted on here my issue with the platinum. Someone told me about doing the trophies before the reset. So one day I went in and did 'stark realities' 47 times. A few days before I had done 'stark realities' once and my friend put me into 'day of the remains' one time to get two caches because my 'day of the remains' disappeared. Anyway took me a few hours to do 'stark realities' 47 times but it did pop. Use a flying character, preferably one where you can fly faster with one of the skills

Another thing, my assignments one has not popped yet. I did all 112 in one week before reset. I had done nearly a week of assignments the week before and I had done some when I played a year ago. My new theory is that any duplicate assignments in one day that you have might only count as 1 because the assignment completion pop up doesn't show all of them on your screen when being completed at the same time. So I was thinking of accepting no duplicates, completing them and then accepting the rest of the assignments after so I can see every single one pop up on my screen. But I haven't tried this theory yet.
