Hi, I am playing New Vegas over Christmas break and was wondering about two glitches I've encountered in my few days of playing.

1. A friend told me the Ninja perk is completely screwy and not to get it even if you prefer hitting things over shooting things, specifically that it doesn't add 15% critical chance but multiples by 1.15, which long story short makes it a waste of a perk and the strenuous stat requirements needed to get it. Has this already been fixed in any of the patches or will it be fixed in the next few days? I heard programmers have to take lots of math classes...I guess not? Haha.
2. My comrades constantly die, and I finally figured out it was because there is a glitch where the companions poison infliction never wears off, making their chance of death 100% at the encounter of any and all carozons, or whatever those weird looking bugs are called. I sincerely hope this is being fixed, and if so I would like to know when? I have to go back to grad school in a few weeks anyways, but maybe if I'm lucky y'all will have this fixed before I stop playing the game and I can resume using companions which I hear is a critical component of the game.

Thank you for your time and happy holidays!
Nick
