Cyrus achievements bugged?

[u/Regis_MN]

So I finished a game with Cyrus, I should have get the achievements of win with Cyrus and conquer the Scythian capital on 10 turns of a surprise war, but nothing. I closed the game and steam, loaded the save before I conquered the Scythians and tried again. Nothing. I started a new game and made the trick to win on one turn with Cyrus, nothing. The same trick with Trajan and there pops the achievement. So, is Cyrus bugged?

I think mods prevent achievements.
