I have been leaning towards then trying to tell us there are still stuff to be found in Payday 1. Lately I have been going back and looking over everything again to see if there is anything I didn't notice before. The big thing that makes me think this is the four pictures of the Safe House that are all from Counterfeit. Two of the pictures are of Undercover. It just seems too blatant to me.

Did anyone notice the four pictures above the laptop in the Safe House are all from Counterfit? I found the boat twice in Wilson's basement. The rooftop picture I found once near Mitchel's kitchen. To me it looks like it is from Undercover, but I am not sure. The picture of the tall building I found three times. One instance of the picture by the TV in Wilson's house cannot be knocked off the wall by the player. The stairs are a picture from Undercover showing light beams coming from a wall on the first floor which has no doors or entrance like the other floors do. I managed to find it five times in the map, one of which in Michel's house is placed upside down. I am wondering if there is some significance to these picutres since they seem to have brought them back in Payday 2 and they are all found on the same map originally.
