I am trying to merge the BTB edited version of Darknuts GDR, with the Mountainous Red Mountain (Piratelord) compatible version of GDR made by Knots

I tried copying all the landscape and cell edits made by Knots MRM compatible version of GDR, and pasting them into BTB's version of GDR, but i get these errors in the construction set.

Object reference "terrain_rock_rm_19"missing in master file.Current file "DN-GDR BTB MRM.esp"Cell "Red Mountain Region"Object reference "terrain_rock_rm_19"missing in master file.Current file "DN-GDR BTB MRM.esp"Cell "Red Mountain Region"Object reference "terrain_rock_rm_19"missing in master file.Current file "DN-GDR BTB MRM.esp"Cell "Red Mountain Region"

But i checked and I am loading both the MRM and GDR master files. So i'm confused as so what the problem is
