The Drewcase Era, or as I call it "The Drewcase Error." Talk about growing pains.
Don't mean to chime in like an otaku here, but if they only ever air a select few episodes of season 37 because of the issues the season had, I would hope one of those episodes includes an exception for the "Drewcase" on the Election Day 2008 episode (11/4/08), which contained the "One Week" showcase (which showed Rachel dressed in a - albeit, poorly colored - Sailor Moon costume).
That said, however, from my understanding, it was said that the s37 episode that had Jack Wagner (03/06/09) was slapped with the "do not reair" label due to how extremely negative the episode was reviewed... I cannot confirm that for myself, however, but it would be understandable if this episode never airs again.
