The mod makes all merchents except peddlers, hunters and merchents that need to die for quests essential.
Which means that they will no longer be killed by vampire and dragon attacks.
If u find a merchent that is essential but i want to kill him/her/it
u can the following command in the command prompt to change the essential setting of that merchent
setessential <merchentid> 0
Current update doesnt include the dragonborn dlc, might add this later on.
