[GAMEPLAY] Zoe Spell Thief Snowball Conflict

I've found a bug only reproducable on Howling Abyss or anywhere with a Snowball summoner spell. The short version is, when Zoe picks up Snowball used by an enemy with her W, she can throw it and use the followup properly. However, if she picks up another summoner spell while her snowball is in flight, when the snowball lands and she gains access to the dash followup, it will still overwrite whatever she is currently holding, but not disappear in a few seconds. The icon by her health bar will be an empty icon, and when she actually uses the ability, nothing will happen. Well, the damage orbs still show up, but there is no dash or other summoner effect.

I have reproduced this issue several times, and it's very easy to do with 100% accuracy.

1. Enter a custom game with another player. Make sure the enemy player has snowball.
2. Zoe and the enemy player walk to the center of the map.
3. Enemy player throws a snowball.
4. Zoe picks up the snowball.
5. Enemy player uses another summoner spell.
6. Zoe throws the snowball so that it will hit something.
7. Zoe picks up the second summoner spell while the snowball is still in flight.
8. When the snowball lands, the bug will be apparent.

If this is not clear enough, I would be happy to demonstrate at some point.
