Creating new actors, or duplicates?

[Deleted31005User]

My question is:

Is it necessary to create new actors for npcs or can you just duplicate an existing actor and use that one?

Im asking this because I made a few npcs out of duplicated actors but ever since I introduced them into my mod people have been experiencing CTDs, any version before the npcs seemed more stable.

I edited those new actors and put "actorbase" to "none", changed ID as well and deleted all previous factions.

 

So before I make all new npcs which I really don't want to do I hope someone can tell me if this might be the cause.
