Respawning at checkpoint after boss dies to poison blocks progression

Bug Report ID: #2319999613

This is a pretty weird one. I was fighting and died but had enough poison on him for him to tick down and go into the death cutscene/animation.

After letting the animation play out and loot dropped I respawned at the checkpont. His death animation started playing again but this time he shoots across the screen. He does this every time you respawn at checkpoint.

I'm sure resetting the area will be fine but at the moment quest progression is blocked as the door to the excavation site does not open.
