Error in "Training Mastery" achievement

I tried to close all achievements. But one achievement for trials and the Normans (all campaigns are closed) does not want to be closed and even activated. What to do? How to solve this problem? I played offline for a while on Steam offline, maybe that’s why it didn’t count? Has anyone had this problem (achievement hunters)?


Thank you for reporting @Paradox75831004! This one is a known issue that should have a fix coming. It will likely not make the next update, but probably the one after that. It will more than likely come in a full update, not a patch.
