Crash loading Victory Screen resulting in loss


Twice now when I have won a match, just when the Victory Screen is supposed to load the game crashes and when I go back in to the game it has counted as a loss.
At first I though nothing of it, the game does crash for me every now and then outside of combat, but now twice in a week after a win. The first time resulted in a GW loss, the second in the end of a Delve, so both pretty annoying especially as I had already won!
I am playing on an iPhone 6S, this Victory Screen loading crash has only started happening about a week ago, possibly with the latest update? Not sure.
Thanks for an otherwise great game!
