Attempted a Mongol Empire achievement run this past week, encountered the same issue. Additionally could not get Steppe by Steppe or SPQR to unlock despite holding all required lands & titles (converted to feudal/made ERE primary for SPQR after other achievements failed to trigger).

Pax Mongolica, Go West Young Mongol, One Arrow, Red Sea Resort, and What Schism? all unlocked correctly.

Anyone found a workaround for broken achievement triggers associated with de jure land requirements?

EDIT: Got all three achievements by loading a backup save from 10 years prior. Conquered territory in de jure Abyssinian & Tibetan Empires this time (not clear that made a difference). Also disputed all independent barony-level holdings (Teutonic & Bektashi Orders) and usurped the duchy of Latium from the Pope BEFORE completing the conquest of county-level and higher independent rulers in the required territories. Maybe the order of actions matters?
