Which achievements are bugged?

Hello there, this is my first post here. I just got a doubt about achievements in the server (as I'm really addicted to accomplish them), which achievements are bugged or cannot be completed? I know that MIX server has the achievement "Win a DD map on fire" bugged because I tried it in several times and I didn't get it. Which others are bugged in Race Server or Mix?

I got 32/32 on mix, so it should not be bugged

It is the only bugged achievement. Between the 33 achievements you try the bugged one? xD All other achievements works fine no worries.
