Every Halo game has them. It is almost impossible to for the creative teams to spot and fix every one of them. I counted at least 30 instances so far, of texture uvw'ing messups in Halo Reach. And we aren't talking about ambiguos out of play area ones either. We're talking smack dab in the middle of a map. Take a walk through the Oni level, and tell me how many on that level you see during your regular campaign playthrough.

also on beaver creek, are smoothing group mess-ups on the rocks beside the bases

This sort of thing really doesn't matter. This Forum acts like little things are going to destroy the game or the art, but in reality every game has little errors that probably aren't over-looked they are just ignored in order to deal with more important art issues.

To reiterate what YakZ just said; the thing that people do not get about fixing small bugs (such as graphical mistakes) is that when you attempt to fix one issue you may be creating another so even when a dev is aware of the minor issues they may decide to leave it or put it on a list of things to patch out later.

On longest, one of the thin walls has a stretched uv error on one of the triangles.
It happens. All games have them.

I wish i could play halo 2 online but last time i tried it halo 2 screwed itself up and i had to reinstall and set up all the skulls again

I had the Same issue! The stupid game starting crapping out on me, and had to do a complete registry and program wipe.

Yes very annoying indeed. Had a lot of fun playing through again on legendary to set up all the skulls

sory for the bump. But i think the not being able to go online prob is something to with an ofline profile

Yeah, getting Windows LIVE to work for h2v just sucks. It would always like hold up while it was connecting\signing in and never finish. So I would have to use task manager to quit h2v. I had to do this like 18 times until finally randomly it decided to work in a decent amount of time and not freeze up.
