I don't know if this even counts as a bug but while waiting for the patch I was fooling around with the char. creation and noticed that when i added a beard to my char the eyebrows changed. The changed color did not match the original intended hair color. Perplexed I switched from new-vegas to fallout 3 only to discover that the same thing happens upon adding a beard in fallout3. I know this is such a trivial matter compared to the DLC bug (which i suffer from) but it it leads me to wonder, aside from multiple factions, hardcoe mode, a lot of inviso-walls (not a good innovation in my opinion), did obsidian really try to improve the game from fallout 3 or did they simply rename and repackage?

If there's a bug unaddressed in F3, you can bet your life its still present in New Vegas, i have found a few of these unfortunatly.
