Okay, so using the GECK, I want to create a unique Trail Carbine by modifying the existing Trail Carbine and then hitting yes to make a new entry when prompted, my question regarding this is when I save it, it asks me to save as, and I would need to save it as my own .esp, is this going to affect anything except add this unique trail carbine to the game if I run this .esp? Second question, I load up the falloutNV.esm and only editing the fAutoAimMaxDistance to something higher, then saving as a seperate .esp, will there be any repercussions or difficulties when running this esp that only modified the autoaim stemming from the nv.esm, sorry if the questions seem noobish, i'm not a modder.
