So I got myself a copy of fallout new vegas to play. Everything goes fine except mods. I use the Nexus Mod Manager and have followed every single step on how to download and install mods. So my problem is that everything goes fine, the NMM installs the mod but at the moment of running the game it is still vanilla. I have already checked if the .esp mod files are selected, they are installed, everything seems to be functioning correctly. Yet they won't appear in game.
¿How can I fix that?
