I've done all the collectibles and I mean ALL, 176/176 Mementos, 68/68 Tapes, 71/71 Graffiti, and yet not a single one has given me an achievement. The only reason I can think of why this is happening is when I went to China for a week and didnt have wifi connection to my computer(which is why I even wanted to get the collections in the first place I was a bit bored). Do I need to regain them all over again?
