Double card bonus + Double card for 250 diamonds issue

[Janus]

Actually now that you mention it, I watched more closely, and either I'm mistaken in my understanding of this, or you're right, and mine isn't working consistently EITHER.

Just got 4 cards, even though as I screenshotted above, I got 8 under same conditions (inferno 1, diamonds cards & the 2x bonus event).
