This has been happening to me on the Xbox One platform, whether I am in a battle or just at the menu to start a battle, when I click on enemy heroes, the game freezes and then crashes.
It happens every time, but seemingly only in Suncrest and Construct. I don’t know if this is because those are the two kingdoms that blood frenzy is currently active in as I am writing this.
This does not appear to happen when looking at other troops, only the heroes.
