Ursprungligen skrivet av jerk store:

This guy is right, I've been running it for 4 or 5 hours straight and games are only saying 1 hour or so and not dropping cards like they used to...seems like the sale has borked card drop times or just game time count in general.

If you ever refund a game then it changes the rate at which cards drop with the first card going from dropping after 5 min's* to dropping after 3 hours.

*This applies to older accounts, newer accounts also have slow first card drop.

Bad time to be idling, Steam servers are more flaky than usual due to the steam sale causing them to be busy.

Not 100% sure what you mean but...

Once cards have dropped for a game they will not drop again - see the badge page for drops remaining.

Steam only drops half the cards for any game, you have to buy (or trade for) the rest or craft booster packs from gems.

When it said reading badge pages - did it get your number of badge pages correct? check the number of badge pages when logged in to a browser like Chrome, Firefox or Edge.

If you want cards, buy cards.
