Not getting rewards after finishing a game with a tie/loss? [BUG]

So I was playing against a Fiora and she already had killed 3 minions. I was attacking and the opponent decided to block with Fiora to kill one of my minions, however I had a shark at the end of the playing field which was going to deal lethal damage to my opponent. I wasn't sure who was going to win here because Fiora's effect was going to happen, but the opponent was going to be at 0. After the attacks went through, the opponent went to 0 and Fiora's effect happened, thus I lost. Then it sent me to a screen that said, (and I am doing this from memory, but someone must know the actual error words.) "Timed out before experience points could be granted." This screen popped up immediately, so I don't think it was supposed to show because in my opinion, there was no time between the game ending and the next screen. I have only seen this once, but I believe it was because it didn't know how to deal with a tie, but what do I know, just trying to help :).
