On a network client the overshield's drain arrives with the host's updates
after the HUD has taken its last shield value for the tick, so every frame
the shield looked a step lower than the HUD remembered and the shield
damage sound played for the whole overshield. The Xbox plays nothing.
The meter's flash already told the drain from a hit (a step of 0.05 or
less from past full); the sound now uses the same test, so a drain is
silent on host and client while a real hit on an overshield still flashes
and sounds.
