Free Medivh heroic Paladincrash

Hey! I try to play one night in Karazhan on heroic mode and it always crashes on my iPad Pro and on my iPhone X (newest updates are installed) by choosing an Anyfin Paladin. It also happens most times by trying to play a wild Warlock. I also tried to play a priest deck and most time it works.

I don’t know what’s the reason why it crashes but it’s double tricky than Nazra on heroic already :wink:

Thanks for your help!
