OnHammerHit hook issue since last update

So after yesterdays update (

2.0.5449)

This hook is not triggering for SOME players, mainly buildingblock structures.
I have made sure their client was up to date and I also had them verify game integrity

Can we take a look at this hook?

This is my simple test code

object OnHammerHit(BasePlayer player, HitInfo info)
{
Puts($"{player.displayName} hit something with hammer.");
return null;

}

And I can verify that it works for some players but not others and it depends on what kind of upgraded buildingblock they hitting, for example Player A will register when hitting a stone wall but it wont register when they hit a metal wall for example. 

Thanks in advance.

The hook hasn't changed and still exists in the game.

I dont know why this went under Remover Tool support but ..my own plugin hasnt changed in months and problem only started after last update, is it Oxide or Facepunch change? Can you take a look at it when you have a chance? 

Thanks in advance @Wulf

@Wulf quick update, this maybe a Facepunch issue since native in game repair with hammer doesnt work as intended either, if ur facing a certain way it will work
