I've spent the last couple of days tweaking mods before coming back to New Vegas and I noticed that my merged patch in FNVedit was coming up empty. I'd previously dragged over a couple of weapon fixes from Yukichigai's Unofficial Patch into Sawyer's mod and had to add YUP as a master, for some reason FNVedit wouldn't merge any lists from these two mods while the dependency was there, removing the edits and the master dependency solved the issue but I don't know why. Can anyone wiser than me chime in with an answer?
