Fallout: New Vegas

[Secura]

Currently I've got two bugs that are really irritating me; firstly, I cannot find Loyal anywhere for his contribution to Raul Tejada's personal quest. For some reason, he's apparantly teleported from Nellis to Black Mountain, but he's stuck inside a rock and cannot move, nor can I reach him to even engage conversation. If it wasn't for the fact I still have Caesar's quest to win the Boomers over/kill them, I wouldn't have a clue he was here. >.<

The second bug prevents me from progressing through Veronica's personal quest; when trying to enter the Gibson Shack to access Elijah's notes on the C-Finder/Vault 22/Pulse Gun, the game freezes during the loading phase. It's done this around five or six times now, so I've kinda given up with these two companions for the time being.

EDIT: Alright, found a way around the second one. Once I dismissed Rex, I was able to get inside with no freezing. Darn mutt. :P
