The error there is yours. You shouldn't be searching "3068bp*".
If you go look, nothing is named that. They just put the old numbers in as
alternates so people who were unaware of the change will be able to find things
labelled with the old numbers. You are aware of the change and should only be
searching "3068p*".
If 3068b doesn't exist anymore ALL the 3068bp should change to 3068p
They did. You are finding the same pieces in both searches, except the "bp"
search will omit new ones going forward and also the peeron, LDraw, and I guess
Star Wars ones.
