Viper Napuatzi Boss Fight Shield Wall Bug

So in the fight against Viper Napuatzi you can apparently become part of the shield wall when it closes in when she gets low health... I have managed to get stuck in the dude holding the shields and spears, which made Viper spasm out and walk into a corner, but didn't allow me to do damage or even move... Might be good to fix. To recreate this, I think I rolled towards the shield wall on the right long side and phased through as they moved in....

One time for me Viper even moved on top of one of the shield guys lol. Also somewhere along right side.

Manage to get the boss stuck outside the shield wall somehow and could no longer target the boss. But the boss could still target me. sheesh
