I wanted a mini mod to help protect those silly npcs who like to play hero and get killed.  Or are victims of the Sands of Time Ultimate Deadly Encounters mod, which is just as likely. 

The features are:

1) Will either automatically or manually resuscitate dead npcs, even if they have died before this mod was installed.
2) When they revive an attempt is made to put them in bleedout, for higher realism.  Not always possible. Some npcs refuse that stage.
3) There are several triggers for reviving the dead npcs.  If reviving a dead one from a while back, stand next to them and EQUIP, not just ready, a weapon.  Does not matter what weapon.  So if you have one already equipped, unequip it and equip it back. Simple. Being hit in combat is another trigger.
4) Will work with all dlcs and addons. ACtually, requires all DLCs.   Does not matter if the npcs are new.  What does matter is their faction. 
5) The mod will use some resources in automatic mode.  Almost none in manual mode.  Manual mod uses two spells you can give yourself in the mcm menu.  A RESURRECTION spell and a FORGET spell.  The forget spell will stop combat,comabt alarm, and clear all bounties.
