Serious reply... are you sure it was milk chocolate to begin with (wrapper etc) and was there still peanut butter in the white chocolate (white chocolate peanut butter?)
In addition did the chocolate partially melt in flight (in a pocket etc)
A cursory web search did not show any link to pressure and milk chocolate to white chocolate conversion however I do recall something about melted chocolate having as different slightly different appearance when it solidifies

Cadbury and Nestle are working on a pressure/moisture resistant packaging in collaboration with NASA
I remember the way cool tubes they had for the food back in the Apollo days. Just like toothpaste roll out the food hmmm....
Oh well I hope someone has a definitive answer for your mystery
