Wilba Reform's frames past 121 are mistakes, specifically, they are frames that should belong to transform_pst animation, but have been accidentally added to reform.
This causes Wilba to "bug out" when switching back from Werewilba - Where she switches back to Werewilba for a handful of frames (the mistaken frames)
