My game won't update because it claims that I need at least 40,9gb, but at at DOWNLOADS the seems to have only 46,9 mb, also I have 24,9 gb of free space im my drive, soo, what is happening and what should I do?

EDIT:
People on steam discussions told me that SQUAD had the SAME issue, the problem is related with the UE4 and how the update are deployed, they later fix it. NW should get in touch with them because it will be really frustrating if the game releases that way.
