What's the problem here?

[ZerBea]

I don't know. Did a update tomorrow from (v3.00-beta-11-gd0123e6+) to (v3.00-beta-25-gb5cb29a)
and none of my testlist word are found.

try this one please:

http://hashcat.net/misc/example_hashes/hashcat.hccap

password is hashcat!

[ZerBea]

I'll check the git history to find the last working commit beetween beta 11 and beta 25 using hashcat.hccap

[ZerBea]

Last working commit (using hashcat.hccap and my my test.hccap) is:
1d797a1

Updating to this version causes the error in both (hashcat.hccap and my test.hccap):
0ddb264

It seems, that packv() and unpackv() didn't work as expected.

ATTENTION!
The wordlist or mask you are using is too small.
Therefore, hashcat is unable to utilize the full parallelization power of your device(s).
The cracking speed will drop.
