Repacking game files breaks the game

[exurd]

Unpacking and repacking the same files from the packed files stops the game from running.

The commands I used to repack: C:\f\e>python3 C:\f\fezpak.py unpack C:\f\Essentials.pak C:\f\e>python3 C:\f\fezpak.py pack Essentials_repacked.pak

Also, note the different file sizes.
