Yes, it was a bug, it's fixed in the last version already released. That will go public once 1.4 is the last one.
If you have 1.3 please tell me what card numbers are missing.
Thanks very much for reporting.
For diamond it was 73, and for ruby it was 68
yeah, those were fixed in the last release.
Next week I'll probably release a new version and current one will be free.
