I also had this problem recently at first I thought it was the pauldron but then I noticed that when I built my helmet the entrance was to tight under the chin that I had to really force my head in and turn the helmet but then I had vision issues, I thought if I cut it I would mess up the helmet but I took the chance and cut a little more beneath ( between the chin and the neck) the chin area and the helmet fell right into place I even was able to remove some of the padding from the inside for more space. now my helmet fits better , the chin is not resting on the pauldren and I have more freedom of movement.
