1. Doing the Oh, My Papa quest and Melissa is the only one I need to convince. Since I helped her earlier with her side quest, she is no longer at the Great Khan encampment, even though the quest says she is. Anyone know where she is??

2. Isaac has disappeared. He is never at Gun Runners and I've been there multiple times to give him scrap metal. Where is his house??

3. I'll take Raul to his shack and he still gives me that smart remark, tells me to take him to his shack, and won't repair my things. I've tried this inside and outside his shack. ??

Any help would be appreciated, thanks.

2. South of New Vegas Medical Clinic there's a few houses where 3-4 families live. I believe Isaac lives in one of them.

Isaac is in the second house.

3. it happens with me its a bug
