We actually kicked this around for a while in the studio not long ago, and eventually reached the conclusions that:

a) Matters were very much disorganized in Valhalla and Fólkvangr at the end of the war, since it was such a busy time for them and they were in the midst of a transition of authority (Skuld was just coming into office during the war), and there may have been a few dropped balls;

b) The I-400s' disposal was rather less eh... public than those of Nagato, Saratoga, Sakawa, Prinz Eugen, et al.;

c) Don't investigate this too closely.
