Either you ran out of cards or you've hit one of the games which take longer to drop. If it's still idling a game, just be patient. Some games can 2-3 times longer than others.

Bought a bundle today, got like 47 new cards to drop aaaand theyre not dropping. :/

Be patient. If it hits 5 hours without a drop then you can feel worried but until then it's nothing anyone can do, steam is just reluctant to drop at times.

If you're idling multiple at once, change it to 1-by-1 as that is faster. Beyond that, I got nothing else to offer.
