what should happen - when lux's shield returns to her, "the returning wand shields for twice the amount, for the same duration, while also stacking with the outgoing shield and resetting its duration".
what actually happens - the shield increases for allies, but not for lux herself. [here's a video demonstrating it.](https://drive.google.com/file/d/11es8mx04dLjNqe6g9tAOErd8fQnR-FG6/view?usp=sharing)
i'm not sure if this happens for every lux game as i only noticed it several minutes into this game.
