I reproduced the problem using your VTPK. I have sent the repro case to the dev team. I do not know why this .vtpk is not packaging correctly. Potentially this problem could be worked around by manually updating the MMPK, however its not possible to enable for anonymous use when modified manually. Fixing the path problem is just a matter of unzipping (7 zip) the MMPK. Copying the original VTPK into a folder in the p12 folder.
Then update the path in the map_with_vtpk.mmap to reference the .vtpk file in the folder.
