Yeah I was using the nightly build you had linked rather than the release from Nov18th.I'm not sure what you mean by "re-compress". I know there's an option to compress archive back using LZ4 or LZMA compression (don't try to load the game when you select LZMA option, it will take forever), but if you already decompressed it there's no reason for you to compress it back.
