Decompression test for Lies of P

*.pak

38 gb > 73 gb
ue4d by Shegorat + xtool v0.85 + zlib (without reflate because decompression errors).
-d1 for xtool parameter is required

For which reason did you use "ue4d"? Also if the game looks encrypted the decryption tool is not needed, I tried directly with zlib+reflate and works.
