Okay so this has happened about 3 times since the expansion. The last game was UD vs ST. The units on the map before the game ended were Siege Monger, Screaming Imp (summon), Frostfall Vanguard, Nefari Shockbow, Pinchusion, Limited Jakei Extinguisher, Lonx Adept, and Globe of Deception. I used Ice Storm to hit and destroy Seige Monger, while injuring Screaming Imp. After I attack Screaming Imp it was destroyed and the server error occured.
That's probably what happened. The Ice Storm chilled the Screaming/Bloody Imp then when I killed Imp with Frostfall Vanguard I assume the equip triggered and the Server Error happened.
That is what appears to have happened from what we can see on our end. This is something we are working on resolving.
