I'm not sure if this is "Kif GKUaN" continuity or whatever, but I just noticed it upon re-watching "A Taste of Freedom".
Okay, first off (according to the p-code), in this episode (4avc01)...the Nimbus is intact. Later, the Nimbus is destroyed in "Taste of Freedom" (4avc05), then, later in 4acv, in "Where No Fan has Gone Before" (4avc12?), the Nimbus is fully functional.
Fox reversed the whole ordeal. The Nimbus is fine in s4e12, destroyed in s5e04, and rebuilt in s5e05. I wonder if there'll be an explination?
Wizard drive is not acceptable.
