Didn't get achivment for complete Mongols campaign

[IfElse101010]

I just complete the whole Mongol Campaign and didn’t unlock the achievement “The Mongol Empire”.
I’ve completed 2 campaigns (French, English) and got achivment.

What I should do to get this achivment? Support can help me?

Achievements Will Not Trigger if You Load a Saved Game

I’m having a problem with campaign achievements in Steam not triggering. Other non-campaign related achievements triggers just fine, just not the ones related to the campaign. For instance, I recently completed the Norman campaign, but the achivement won’t unlock. I’ve tried both restarting Steam and my computer, as well as reviewing the game files and checking integrity. Anyone else having this problem? Is there a possible quick fix?
