there's no way to check what survival maps you have medals on is there?

The only maps that valve tracks are the original ones and not the new ones. Which means playing them out of order for the achievement will mean losing your place easily when going for gold medals

Give them some time and they'll add them to the stats.

So it turns out you technically can check by selecting each individual level, but man that still takes a while to figure out if you're missing one. Here's hoping they do add all the maps to the profile leaderboard

Once we get the achievements working properly, you'll be able to check your progress under the ACHIEVEMENTS tab in the main menu. Valve is also aware of the missing stats on people's profiles, it will be added after we take care of more pressing issues, like the server crashes.
