Companion Level 3rd Star Not Awarded. Level 712 still says Unlock at Level 711. Why?

Hello @dwb

How are you doing?  It has been a while since we talked (I mean I have seen your posts)  

OK!  With regards to the issue with the Companions level and your achieved stars, try this::  
Close down / Force Stop the App  -->  Clear cache  -->  Restart your device after shutting it down for 2 to 3 minutes  -->  Now, log into your game again and check if your 3rd Companion is unlocked! 

If not, please post back along with your game user ID number with the help of this link  https://community.king.com/en/farm-heroes-saga/discussion/247379/what-is-my-user-id-and-where-can-i-find-it

Talk to you soon!  Have a great rest of the day/evening!
