Why can not my friend who plays in a different league , level 5 has my players can make an offer. I myself have Level 7 Although another of my friends list looks the button , but can not push this Make Offer. Why is that?

There's a few things that this could be, the player is on a another server, the playes stars is unders 3, the players stars is over 5. Hope that helps.

Es gibt ein paar Dinge, dass dies sein könnte, wird der Spieler auf einem anderen Server ist, der spielers Sternen under 3 ist, die Spieler mehr als 5 Sterne. Hoffe, das hilft.
