Basically, I've been wanting to make some small scale balance changes to the game to go along with all the mods I've downloaded. All going well untill, saved an esp then continued the next day and found a bunch of duplicated (DUPLICATE000) references plus the original unchanged ones in the geck. I've tried looking around for answers and have come across the face that all the plugins I have loaded, except for the one I'm editing, need to be set to master. Is this right? (Currently it's a bit of both, basically loading all my mods, and making a few further changes).
If so, the trouble I'm having is in converting esp files to esm, FNVEdit seems to be the best choice for this, only following the instructions I've found, I'm supposed to change a setting in the File Header row, yet no such setting shows. I click on File Header and it remains largely blank on the right hand columns.
After getting frustrated I thought I'd look for some active help, I'm probably doing something stupid or missing something minor. I realise I could just leave the changes I want to make only I appear to have become a bit of a perfectionist in getting my game set up exactly how I want it :< Just hope people are still around for New Vegas xD
