Sivir Shield Does Not Block Anivia Stun
Played a game as Sivir and used my E (Spell Shield) to block an incoming Anivia Q (Flash Frost). I saw that the shield reacted to the spell, blocking the travel damage, but not the explosion/stun damage. I'm not sure if this is intended as Flash Frost does seem to react as 2 separate spells (the initial missile and the explosion AOE); however, as it is, there is very little opportunity for Sivir to actually block the stun. unless she shields the moment the projectile stops, she will block the first instance of the spell and not the second.
Please look into this as it is a potentially game-breaking functionality issue.
