## Description of the bug
I hauled a crit survivor while stood on top of fire and they died right as they were hauled. This left them on fire but still hauled and I was able to carry them even though they were dead and unhugged.

## What's the difference with what should have happened?
The survivor should have been force dropped upon death, I shouldn't have been able to carry a dead body around.

## How do we reproduce this bug?
1) Put a survivor into crit
2) Haul them whilst standing on a fire tile
3) If they die right as the haul is finished due to the fire damage they should remain hauled while dead
