I've posted a topic similar to this a few years ago for another Netease title, Harry Potter: Magic Awakened, but now I'm facing a similar issue with a different Netease game titled Identity V where I'm now unable to export assets for some of the games NPKs due to a "uncompressed data" and "compressed zlib/deflate input is wrong or incomplete" error (example included below of the error) when trying to use QuickBMS.

If its necessary information, I'm using the .nxpk script when trying to export the NPKs.

Code:

. 00000100
. 00000000 idstr              "NXPK" 4
    4e 58 50 4b                                       NXPK
. 00000004 get     FILES      0x00000add 4

. 00000010 get     VER3       0x00000001 4
. 00000014 get     OFFSET     0x003d6e78 4

. 003d6e7c get     OFFSET     0x00234634 4
. 003d6e80 get     ZSIZE      0x0000025a 4
. 003d6e84 get     SIZE       0x00000e2b 4
. 003d6e88 get     ZCRC       0xf5b02114 4
. 003d6e8c get     CRC        0x44e892da 4
. 003d6e90 get     FLAGS      0x00030001 4
  00000000 3627       00000000.dat

Error: the compressed zlib/deflate input is wrong or incomplete (-3)

       result      0xffffffff -1

Error: uncompressed data (-1) bigger than allocated buffer (3627)
       It usually means that data is not compressed or uses another algorithm

Last script line before the error or that produced the error:
