I had to adjust several holes so the screws could go through.  I also had to figure out which screws to use in two instances since the instruction book obviously listed them different than the packaging did.  I had several spots where the walls rubbed during shipping and had marks that spot paint would be nice to fix.  I also had two of the roof supports crushed during shipping due to the box being smashed and am awaiting replacement parts to finish it.  Also how the heck could you ever use the plastic ground screw covers once you have it set up? Does superman come to life it up to put them in the ground below the walls once it is complete?  Geez.
