I deleted and retry the import today because I thought I might be a problem with previous import.
I imported a V8 Brain with (12 Thought Types) into V9 today.
V9 says it has 12 Thought Types, but if you look at the Thought Type list there is more than 12 (Actually it 24, it double up) also all my colors didn't come across.
Matt already had a V8 BrainZip of this Brain.
V8 - Showing 12 Thought Types
V9 - Showing more that 12 Thought Types - All Colors Gone
V9 - Stats
