My case is similar to another bug but little different.
I can not tell what I have not passed on art of war even with the latest steam counter update fix.
When I use steam for gaming, I have notice that the art of war medal record from xbox account(different account) has been transferred to my new account(steam one) directly. But I do not have all golden medals at that time.
I have finished all golden medals on steam version few months ago.
But I still can not unlocked “Record Breaker” Achievement. I think my steam profile have crashed with xbox version profile and it affects art of war medals counter forever.
I have waited 2 major fix so far since April 2023.
After new major fix has been published, I tried to trigger the art of medal detection again by finishing one of the medals. But this issue is still not fixed. I am in aoe4 version 7.1.1130.0 now.
