my FTL & Torchlight2 'no longer eligible for a booster pack'?

No, it shows that text before you have the L5 badge. You can still get booster drops.

I see nothing wrong here. If you click "how dp I eran extra cards" you can check if you're eligibale for booster packs. For me it shows the same for many games

I got it the same by lvl 1 of TF2 and Magicka badges, but at my LVL 5 Terraria I can get the cards boosts.... Strange...

it just a 'text glitch'.
if I click the badge (go into detailed view),
the text is not missing (no card drops blablabla)
and it still eligible.

sorry to bother. :)
