I have this problem with NEF files from a D3100 that have been edited (even viewing them may be enough) in View NX2. View NX2 changes the raw file from a big-endian to little-endian TIFF wrapper (if you check the header it goes from II to MM). This is on the macOS version of View NX.
Not sure if this is the same issue as @Soren_Garup is seeing but I do still have the camera so I can get some sample files togther if that would help.
