Shield Throw is still bugged. On several of the new maps, the animation appears as if the shield is being thrown into a lower layer of the map. As a result, the projectile goes directly into the ground texture instead of flying toward enemies, making it impossible to hit them from range.
This issue occurs most frequently on new maps or in Monoliths, for example in Woven Echo with Primal Beasts. When standing close to enemies, the skill sometimes executes normally, but from range it often fails.
Same deal with Shuriken. Been a collision issue ever since 0.9. Apparently the underlying code behind ricocheting projectiles is the same for both of these skills.
