Alright so I will post a link to the pic and see for yourself. But there are no live death claws at the deathclaw promotry. It appears that the corpses are unaffected. But All live Deathclasws are gone and replaced with this: (see pics)

I have several mods installed but very few (under 10) and I don't think any of them would effect Dead money. And the last time I installed a mod was over a month ago and my game has worked fine up to 20 mins ago when I installed Dead Money, so it is clearly related to that. Oh actually I do have a mod that changes the level cap (raised it to 60) would installing Dead Money cause problems with that (since it alters the cap)? But even if that is the case how would that effect live deathclaws?
Also, I have not checked quarry junction or Deadthwind cave yet have only checked the promotry.

- I fixed this problem by validating the Steam files and it appears I was missing a file so that must have been the problem. I don't get why Dead Money caused this tho, oh well, its fixed now.

I have those exact same images appear all over my Fallout game in Dead Money and it also messes up my exclusive weapons for Dead Money like the gun and clothes you just start out with.

I have zero mods and the gas that the Ghost people exhale is just a bunch of purple blocks.

Validating the files fixed my problem. I'm not sure how it was missing that file, but hey at least now it's fixed.
