I rember seeing and finding the space bag glich in fallout 2, its were the ladie has the death claw in a shak. in the south east corner theres a well with a mole rat in it and it has the bag in there with the golden wach,
the bag makes it so any item under it is not spent or taken when you pay or give some one a item, as long as the bag is higher then the item your using,
and ive found 2 fallout 3 glitches and one for new vagus, in the pached version of fallout 3 the paradise falls glitch is only part fixxed, and in the unpached version of new vagus there is a ex glitch when you talk to two difrent npc's
