So, I've been trying to add a hat to the t-46d power helmet and it keeps appearing in-game floating sideways I've tried changing it in nifskope* but to no avail... It seems to not really acknowledge any changes made to it and stays the same no matter what I do. Any help would be really appreciated!

*I rotated it 90 degrees to the left.
