[NFP] 1.0.8.4 Clash of the Titans achievement broken

(I don't have Steam in English, so I had to guess this is the name)

So far, I killed exactly one enemy hero with one of mine, but still was awarded the achievement. Maybe I forgot one, which I don't think so, but I definitely didn't kill all of them.

Looks fine to me, you deserve it.
How does the description of the achievement translate in your language?
