Left 4 Dead 2 isn't giving the Killing Spree achievement.

In the past few days, I’ve been trying to earn a gold medal on every survival map. Yesterday, despite achieving a gold medal on every map, I didn’t receive the achievement. I contacted Steam support, and they told me to open a ticket here. I’m not sure if you can help me.

I forgot to mention that on Steam, I already have 42 out of the 43 maps with a gold medal, but as I said, the last map didn’t count.

Hello @TITO2508, similar to the older issue report, please clarify exactly which game and Steam achievement you're having trouble with.

With the game Left 4 Dead 2, and the achievement is Killing Spree.
