Arena is freezing!

When I enter all gold in matches game jusf freezes and all I can do is to turn off game and that means loosing all gold automatically. Why is this happening and can it be fixed? Thank you.

I see the same a few times. Game freeze after 1,5-2 min of fight

Again, battle just froze and I lost 220 milion gold because of it.

Lost huge amount of gold again because of this error. No one can help with this?
