Karl recently reminded me of the post Timeless Identity by Eliezer Yudkowsky, which I noticed seems to be an instance of this.

For what it is worth I didn't see Eliezer discard any values in that post---either when he first posted it or when I reread it last week. He seems to have kept all his values. Everything 'added up to normal' at the end. He just ended up in a situation where he would be somewhat more competent at expressing those values in a reductionist description.
