Personally Made .esp File Losing Parent Masters

[BurningSky93]

Im trying to make a personal mod, which relies on leveled lists which contain weapons from another mod.

The other mod is an .esp file, which I suspect is the cause of the problem im having.

I add the weapons from the mod (WMK) to the leveled lists for my mod, but upon saving and quitting, the weapons are removed from the lists and my mod no longer has WMK as a parent file. This is incredibly frustrating as it means that I cannot add any weapons which rely on weapon mod kits to my own mod.

Ive tried using FO3Edit to change the masters manually, but this doesnt work.

Does anyone know of a solution?

 

Any help is much appreciated.
