I just checked all related scripts and compared them with lower and higher game versions, they are exactly the same.
The achievement description is a little bit confusing though.
There are multiple conditions that must be fulfilled:
1. All available quests from the Kielce districs must be finished.
2. You must finish the daily quest of each Kielce districts one more time after you have reached 10.000 Favor rate.
3. Map must be changed or relogging after point 2 is done.
I have asked Zax to check the database, for that we need the family name of both of you.
Please tell me your family name here or in Discord, thank you!
