[TFT] [Gameplay] Elise spiderling in champion slot.

So in the time gap - after winning a match and before next turn:

1. My friend had maksimum amount of champions in hand.
2. After winning a match there was still one of his Elise spiderlings alive on map.
3. He had high ping. He sold one of his champions and the spiderling appeared in that slot. After trying to move the spiderling, it became an enemy spiderling and couldn't be moved or sold. Screenshot is availible in provided link.

I tried to reproduce that bug with normal ping, but without success.
