Hi Wulf,
Thanks for adding the OnProjectileRicochet hook to the umod. While testing my plugin, I discovered that the hook does not work on some objects (fencing of the ship's upper deck, chainlink fence, chainlink fence gate). I think that this is possible because I asked you to add a hook to the end of the OnProjectileRicochet function, after all the checks of the embedded anticheat. Can you make a separate umod test build where the OnProjectileRicochet hook is at the beginning of the function?  I would then check my hunch. And if it is correct, then make a change to the master build.

 public void OnProjectileRicochet(BaseEntity.RPCMessage msg)
    {
        BasePlayer.FiredProjectile firedProjectile;
        PlayerProjectileRicochet playerProjectileRicochet = PlayerProjectileRicochet.Deserialize(msg.read);
        if (playerProjectileRicochet == null)
        {
            return;
        }
        if (Interface.CallHook("OnProjectileRicochet", this, playerProjectileRicochet) != null)
        {
            return;
        }
...

The hook is located after the anti-cheat, but that shouldn't prevent it from calling normally for all legitimate calls. I don't think changing the hook index would fix anything. 

You're right. I found a way how to get a missed ricochet. If it is not triggered by the OnProjectileRicochet hook, then it will be triggered by the OnPlayerAttack hook.
