Getting stuck in Viper Napuatzi's guards

Happy accident for me, but should probably get fixed

During the Viper Napuatzi fight I got stuck in the line of guards when they moved closer together. I don't know how exactly, I might have been dodging at the time, but it obviously went quite fast. In this state I was invulnerable to most attacks, but was still able to damage the boss.

After the boss died and the guards dispersed I was able to move again as normal.
