Maligaro the Broken, broken; 3,090,401,043

So I broke Maligaro the Broken (Maligaro's act 9 fight). Got him stuck in a wall when using Freezing Pulse alongside the Projectile Weakness Curse. Pushed him into the wall and now I can't damage him since my projectiles stop at the wall, and he isn't aggroing to try leave the wall.

tldr
Act 9; Maligaro the Broken Fight
Using Projectile Weakness on a Blasphemy
Freeze Pulse knocks back Maligaro when he is next to a wall.
No longer able to damage Maligaro and he can't leave the wall.

Happaned to me twice while running overgrown shrine

Yep, just got him at the corner with heavy strikes. Won't go out, the fight is halted.
