Honestly, there might be a checksum, and that could also be the reason why it won't allow you open the save correctly without corrupting it.
I'm not as good as the people setting up the de-/compressor but I know that if you take the instance file, decompress it - then compress it with ought making any changes the file is 100% different byte by byte. It can't be the decompress because it obviously let's you see what we need to change so that leaves one other option.
