I'm the same, totally - most will be until they suffer these seemingly inevitable problems

I see people thinking its just a Vault issue, or that Vaults are more likely to cause problems - perhaps the latter is true but I've had this horrible affliction strike when in the NCR bar, another place (I forget) and of course a Vault. I'm going to keep checking in here regularily now, luckily (?) I've just got back into World of Warcraft (yeah, I know..) and also have a BUNCH to do on Fallout 3 still - The Pitt, The Spaceship, the after game extension etc. so methinks I'm going to focus on that until this is sorted.. If it never is I just hope I can trade it in befoer the general public/game shops realise! That is pure pessimism though - surely anything that is coded can be sorted out?
PS talking about going on rampages - this is actually what caused one of my problems - I changed characters only for them to spit out the armour my old follower had - she had left so I thought "screw it" had a massacre, the screen went blue and that was the start of this problem for me! "What DLC?!?"
