Issue involving minor connection issues mid-match

Ok so, I recently played a match, and it started normally, things were going fine, until I tried to sell a fiora after losing a round, only to have it not seem to work, and then come up with a message that I'm reconnecting, so I was like "ok, alright, little internet hiccup, this is fine", but then, suddenly my fiora's health bar is red, and I cant sell her. I later tried later putting her on the field(the game let me) and it worked, however when the round started the fiora started attacking my team, and the game autoplaced a unit for me as if it wasn't full(the game acted as if fiora was taking the team slot until the battle started), the fiora was placed back on my bench after having been defeated in the prior round, and proceeded to eat a bench slot the whole game
