Refreezing breast milk?

So my freezer didn’t get shut properly and my stash of breast milk defrosted completely. All the milk is still ice cold(colder than the fridge gets) just not frozen solid and there were no ice crystals present. I was wondering why you can’t refreeze breast milk. All I’ve read is that it can lose some nutrients, but if that’s honestly just it I don’t want to lose my whole stash I’d rather refreeze it. I’m curious on all of your thoughts!
