TArray sort - networking problem

I have a TArray of cards that get sorted in a function called OrganizeHand(). This function is called from a NetMulticast function. The problem is only 2 cards are sorted if you’re playing as a client. As the server, all cards get sorted. I also change the color of every card in the hand and that works as expected. Here is the function:

 void ASPawn::OrganizeHand()
 {
      // sort hand - only sorts 2 cards if client
      ClientHand.Sort(AClientCard::SortHand);

      // disable hand - works as expected on both server and client
      for (int32 i = 0; i < ClientHand.Num(); i++)
      {
           ClientHand[i]->SetDisabled();
      }
 }

And here is the sort:

 inline static bool SortHand(const ASCard& c1, const ASCard& c2)
 {
      return ((c1.suit < c2.suit) || (c1.suit == c2.suit && c1.cardValue < c2.cardValue));
 }

The problem was that I was calling a NetMulticast function on the cards (for animation stuff) every tick, which stopped the other calls from going through.
