 The name of the error is - Tried to set a string that is not a valid utf-8 string.
 The error number is - #1745. 
 The full name of the error is - ui / lobby_panel_club_landing.nut # 1745
The error appeared after I invited a friend to my clan. His nickname was in Russian, he changed it to English without leaving the game. Then he accepted an invitation to the club.
After I press "Club" in the main menu, I get an error, here is a screen of the club
      Also, I cannot delete or edit the club. Please help please)
