I just lost a brawl game, which became the last one having lost 3, because lag spikes made all dead minions stay at the arena, mixed up with later ones put on to the arena.
So the arena became a mess that it was not possible to see what was there.
I have screen shots from this, but can’t see that I can upload any here.
(This was not the first time this kind of lag happened, I’ve earlier lost a ranked match bacause of this, around two weeks ago.)
