I came across a bug two days ago that I actually haven't seen since the game debuted. I was doing my typical "grab all the globes first" run on my way to the Lucky 38 (since Mr. House rarely survives long haha), and I noticed Hoover Dam never registered as a location. There was no XP given, no denotation on the map - it was if it didn't exist. I went about my travels but even returning later didn't fix it.

Is this a known issue, and is there a way to resolve it? It's not a huge deal to me as thus far it's the only spot that's done this, and I've never seen this happen prior.
