I was playing an arena game and it got really close , i was able to topdeck luck a +dmg card so i could finish him off and he just dissapeared, game "froze" on my side and the only thing that was "animated" was if i hovered over the End Turn button.
I decided to wait a bit at that point and checked my connection on second screen , it was all fine and no abormalities.
Though it brought me back to the Arena Key screen and i didn't get a win for that particular game..
Sofar i have seen this happen 4-5 times in arena and it seems to me it's a way to prevent you from 'Conceding/Losing the game if it's looking bad for you' because in every game where it happened , i was about to make the finishing blow.
This seems really unfair and it really rustled me up and **ssed me off, any info on this problem and maybe a way to prevent it ? IE: pulling the internet plug makes you lose the game or ALT+F4'ing the game makes you lose the game or Task manager - End process makes you lose the game.
At least that's a few ways i could think you could fix it , i have not been able to reproduce the problem myself ( Nor have i bothered to even try , because this is just lame )
(EU Hearthstone by the way )
