If you shoot the ground past the edge of a corner, and your bullets bounce to an enemy you can't see, you will do no damage. Even though the bullets are connecting. The same problem applies to shooting the ground behind a Vanguard Sumotori. The bullets that bounce and hit it in the back don't do damage if you're standing in front of the shield. Even though the bullets are hitting the guy, not the shield. This should have been fixed in early access. It's a completely unacceptable bug as it makes ricochet damn near useless.
