also dont forget the lucky 38 casino glitch where you get stuck in your penthouse room because you cannot talk to victor to let you use the elevator.
Sorry if these are reposted.
BOS quest line. Siding with Hardin locks up further progression, even after 30 days waiting. Just side with McNamara and you should be fine.
10mm Weathered pistol. Adding silencer makes the visual of the gun disappear but you can still shoot it and causes screen to be foggy.
EDE My Love. If you go to the BOS and don't agree the first time you talk to Lorenzo he won't reply if you try later.
Hard Luck Blues quest. If you go to vault 34 first, part of the quest gets added then later if you go to the sharecroppers and try to investigate the east pump station nothing updates and the quest arrows lead to nothing.
Heartache by the number quest. Talked to Cass and got her to sell company. Turned into Caravan company got exp and update, but quest still shows active yet its all grayed out.
Victor and the Lucky 38. As soon as I zoned into new vegas for the first time Victor spoke to me and I followed him to the Lucky 38. His faced changed from cowboy to cop on the way and we passed his corpse on the stairs. When I zoned in all the bots attacked.
The floor of the train station near the Boomers disappears so you fall through the ground every time you try to go up the stairs into the only room in the tunnel. Drops you back at the entrance of the train station and possibly on a bear trap.
I find it helpful to restart my xbox every few hours to lower the zone loading times. Not sure if there is a memory issue or what, but is a brand new xbox slim.
