Maybe I'm just very unlucky, but since the release of patch 1.03 I have not dropped a single golden card, although I have been purposefully engaged in obtaining them almost all the time. I would be grateful if someone who received gold card after 1.04 note this in this thread to understand if this is bad luck or a potential bug.

I got several gold cards after the patch. Apparently you're just unlucky

Thanks for the information, so I just have to keep fighting the probability theory...
