Recently finished building. I had 2 brown 1x6 flat pieces (tables in the great hall) missing and Helga Hufflepuff got 2 left hands. A couple pieces had deformations and some have very bad grip (dragon wings fall off everytime you touch him, one of the whomping willow branches, etc).
But this castle is an old dream of mine, so I'm happy! Took about a week to assemble
