Perhaps It's just me but I have been having trouble with her. 1: When i finish a quest for her chapter I will get the normal reward/bonus such as the land mine but sometimes the screen/voiceover for getting the radiation reward, which i already did. Fairly minor and ill live with it, however I'm now on the part where i have to injure myself and return, so i head out with some grenades and cripple myself and get about 25% health left, i return back inside and I'm fully healed before talking to her and talking with her only nets me the normal reward. I've tried to hurt myself inside but I get fully healed every time i do or overdo it and kill myself. Killing her or making her leave the store stops this problem.
Sorry for it being long and here is my loadorder http://pastebin.com/Dr9MuTFD
