Auriza Side Tomb Grave Warden Duelist Invulnerable Now?

[Xanestus]

As it says in the title: I can't seem to damage the Grave Warden, even with AOEs such as Wave of Gold (it works just fine on the pots, though.)
Saving & quitting out doesn't fix it, and neither does resting at the grace. Has anyone else experienced this since 1.09 dropped?

I'm experiencing this too. I'm also experiencing a strange graphics glitch with other duelist enemies in the game and they're invulerable too. There's no graphics glitch in the one in the Auriza Side Tomb but he's still invulnerable.

Update: Verifying the files fixed it for me.
