So I checked my Polaroid collection, and I had like ~30 collected at all.
However when I finished the 5th campaign, and clicked all the Polaroids during the final cutscene. After I checked my Polaroid collection, and voila, I had 150+ Polaroids. So the final part provided me all the missing ones.
So here is the question, is this on purpose (feature), or is it a bug?
