I wanted to comment on the Fallout: New Vegas expansion Honest Hearts after doing something on Dead Money, but this afternoon I stumbled upon a glitch that scared the crap out of me more than the Ghost People could hope to.
So yeah. Fallout 3 and NV are pretty notorious for glitches, though I thought something was up when every time Waking Cloud spoke, the camera would pan into the ground or a wall instead of facing her, and I really only saw her from behind after our conversations, then she ran up to me to join as a companion, and then uh… this.
