Amazed that this bug wasn't discovered earlier. A sort of "Death Shield" bug has been found. Basically, when you die and are waiting to be revived, you have a bit of invulnerability, like a shield. The problem is that this manifests itself as a sort of shield, so let's say someone is running from behind your dropped body to revive you. Your dead body will act like a shield to any explosive weapons, like tanks and grenades. At this point it's just another bug to add to the massive pile..
