Should be fixed in 0.3.1a.

Added GameState-checking within ProjectileHitScanner.Update (for use with Leaf Shield).

Version 0.3.3:

• Fixed issue where LightningBoltGroup could create an empty DamageBlob, defaulting to a null element.
• Added checks within DamageBlob to ensure element is never null.
• Added checks within CreatureStruct.ReceiveDamage to handle things if DamageBlob.amount == 0.
