Looking at the code we found out that parts of it made no sense. Asbjørn provided me with a good example demonstrating the bug, so this was quickly translated to a test (BDKPHN-10) and the non-sense code and the issue could be addressed.
The release has been uploaded to PAUSE and should be available on CPAN.
Thanks to Asbjørn for reporting the bug.
