I made sure that after installing a different mod I deactivated the previous one (And checked again before making this thread just to be sure) Its not a mod conflict sadly as I have only had one vampire related mod on at a time. I did however manage to find a mod called nosundamage which actually worked. However it seemed that the no vampire disadvantages mod (or the vampire feeding, I forget which one I last had activated) is what kept people from attacking me. As for the Lithians Nature of the Beast Mod, it looks really promising. I however can't seem to get it working. I have the pop up tell me its there, I have the black heart though its not doing anything and I pressing V doesn't do anything. I'll try downloading a new version of the OBSE just in case its that (though I did download it recently) EDIT: After redownloading OBSE I had a quick look in the readme and it said I had to start Oblivion with the OBSE loader. Despite not getting to tweak the data files before starting when running the game this way (I can still use OMM for that anyway) I did get the Lithian mod working. The problem is that nosundamage is no longer working. I still get vampirism sun damage ( 5 ) though when I toggle the Lithian Conceal nature sun damage (I have it active at the time) I have just plain vampirism ( 8 ) listed right next to vampirism sun damage ( 5 )
