AOE4: Fleet of Foot issue - Marching Drills no longer available to research

It seems that the recent update which made a change to Marching Drills, moving it to a civilization bonus and no longer researched, may have broken the related HRE mastery “Fleet of Foot” which requires researching this tech and building 30 infantry before reaching the imperial age.

Am I missing something? How can I complete this mastery challenge after the recent update?

Hay, i moved your post to the aoe4 Ask for help section :slight_smile:
