So I got a new xbox and decided to beat new Vegas again, this time siding with ncr. My game couldn't obviously detect any saved info, so a new file was made. I picked up the quest to investigate Nipton from ranger Ghost. I talked to boxcars first and then I stealth killed vuples. I did make the dumb mistake of fast traveling back with legion attire, but stealth boyed and ran away without shooting anyone. Now even with vilified rep with legion, they refuse to shoot me. They have the dialog of preengagement but don't open fire. The NCR however stay hostile towards me. I'm neutral rep cuz I picked up Boone as my companion and I havent killed any NCR. I tried waiting a week before going near NCR but they stay hostile towards me, whereas when I go near legion they don't shoot me. Is it possible that because my previous xbox play through is somehow affecting this even though this is completely a new. Idolized legion rep last xbox. Or is Vulpes a NCR in disguise.
