My reputation was either 'Liked, Idolised or Neutral' With everyone except The Legion
Now, after completing the quest 'I could make you care'
Half of my factions have gone of the list in the PIPBOY ?
Im now neutral with NCR, BOS, Legion, Great Khans...? (I can see on the Map)
Why has this happened ?
How can i fix it ? :sadvaultboy:

EDIT: After loading another save, and reloading my original one, the factions have been added back to the pipboy, but most are neutral :/
Why has this happened ?

EDIT 2: After posting that comment, i open my pipboy, there gone again.. For [censored] sake, this is a [censored] piss take seriously..

Help ?

Have you tried talking to any of the factions yet to see if that'll fix it?

I spoke to the NCR, and they act like im a civilian and not that i just helped them a bunch..
Went to The Fort (Whats left of it, i killed everyone including Caesar)
2 Guys, Legion guys, attacked me, i killed them, it said Infamy gained twice, The Legion got added to the Pipboy, but its still neutral...
This is my auto save, i only started playing an hour ago from my actual save, id done 2 quests
'Wheel Of Fortune' & 'I Could Make You Care'
It was fine, up until the point, where i killed the BOS near the end of I Could Make You Care, i opened my pipboy, they were all there, then, i opened it a second time, BAM they'd gone... But i got no infamy for killed any of them, seeing as they started on me for a quest related matter..
This is obviously a glitch as i dont see how that quest would effect my Rep with nearly every faction in the game, it didnt tell me otherwise..
What the [censored] is going on..

I would love to figure out how you did this, I am trying to get neutral with the Powder Gangers again... However, there is one time int he game when your REP with the Legion and the NCR is reset. The legion is reset after you exit the TOPS casino after dealing with Benny. A Legion guy runs up and hands tells you that the Legion has forgiven you of any trespasses up to that point. For the NCR, you are pardonned when you speak with the Ambassador in the Embassy.

This is necessary to permit you to follow any ending path you wish after getting to the strip. Otherwise your actions on the way to the strip could prevent you from taking certain paths at all.

This is also a great way to knock out nearly every quest in one game. Simply do the quests which tick off the NCR and Legion BEFORE going to the Strip. Then get you pardons and start fresh. NOTE, that the pardons neutralize you, but the wont remove local rep. For example, I ticked off the Legion in Nelson before getting my Legion Pardon, but even after the pardon, the guys at Nelson were still angry with me, but only in that area.
