well i can say that yeah i made it with the 1set rb i have a fully work cod just like the reall co rb system but i had the same problem here i cant get to make the 2nd rb npc trak the old skills from the 1set rb so if i did the 1 set rb im gonna get more skills but once i do the 2 nd rb i have only 2 options to keep all the old skills and give the player more skills or take it all and give him a new skills which is gonna cancel the 1 set rb

(
but no worrys i'll find the answer and i'll post it back soon
