Noob having some trouble with master files

[Fallingwater]

I'm trying to modify an existing mod. I am, you see, an obsessive-compulsive alchemist (if I see an ingredient plant, I must harvest it), and I downloaded Gather Ye Rosebuds to make it easier to grab tons of ingredients without wearing out my action button (and my patience). However, I discovered the gathering spells have a magicka cost. My Atronach character does not much like the idea of wasting precious magicka just to avoid the hassle of picking up ingredients.

 

So I opened the esp in TESCS, removed the magicka cost, saved, and what got saved was a tiny 627 byte file with just my modifications inside. I tried loading it after Gather Ye Rosebuds in the hope it'd just overwrite the original mod's settings, but it doesn't work. I understand this is because I need to set the original as a master file in my mod; however, I can't for the life of me figure out how to do that.

Little help? :)

load the mods esp as the active file in the CS and save it.

you would be modding the original esp instead of creating a new one.

and back it up be fore you mod anything to make sure you can fix any mistakes.

Wheee, it worked! Thanks, now I'll gather to my heart's content :D
