MTG Arena bug eliminated 1 of my hand cards from the game
During a Brothers' War quick draft agem, I happened to lose my wifi connection with 3 cards in hand. When I recovered the connection, I had 1 of my cards in hand (Stone Retrieval Unit) out of my hand as if that card was castable from my graveyard, visually it wasn't castable despite I had enough mana using tower worker (screenshot shows the hand a few turns after the last incident). Then, since I couldn't cast the card I tried to close and re-open the game during the match, and magically the Stone Retrieval Unit DISAPPEARED from hand, and it wasn't neither in the GY, nor on the board.
Unluckily I only have the screenshot in which the incident already happened but I'm really frustrating. After I keep farming gold with daily quests and invest 5k on this quick draft I lose games because the game itself MAKES CARDS DISAPPEAR!
