Items: Armor sets grade C: bound vs normal

potential bug:
i have full bound full plate set items, but not give any bonus.
my friend have karmian set, normal body others bound: not give any bonus
we need full normal set items to achieve set bonus?

"s-grade or lower set armor effects still apply if a combination of bound or standard items of the same set are equipped." from ncsof patch notes http://www.lineage2.com/en/game/patch-notes/goddess-of-destruction/changes-to-items/

i want some correct infos from that, thanks!

 

can gm's confirm this bug, also for b/a/s grade?

 

and there is no common items :d to craft duals need common items but there arent is

 

i find infos about.this have only with c/d grade, above is work correctly.

 

i have the bound demon armour set (c grade) bonuses missing, there were there before yesterday's patch !!!

i have the bound doom armour set (b grade) and bonuses are there!
