Is your feature request related to a problem? If so, Please describe:
Somewhat, I noticed that when First Aid is installed, regeneration's don't always work, my assumption is because of how it handles death, restricting it to head/body injuries.
Describe the feature you'd like to see implemented:
Regeneration to work when a player takes full damage to their head/body (head shot attacks or full death etc), and when the player loses all health.

I also noticed a mod that is compatible with First Aid, that allows players to revive other dying players, my request would be to allow players to regenerate when in or before this dying phase.
