maybe I missed it elsewhere but I tried a fresh testimport for 1.1 from vb3.8x and Thread Prefixes are imported properly to backend but none thread kept the existing prefix after the import.
So the importer just did the prefixes itself but not the so marked threads (prefix_id = 0)...Bug or by design?
