Do you have the pics of it's lower pitchers before it stop pitchering? I might be interested.
It's normal to see nep stop pitchering when it's about to flower, this may last up to 6 months or more depending on how fast it recover from flowering before it start to pitcher again

. If that plant got basal, the basal will still continue to grow and pitcher normally.
So any potential nep breeder should bear in mind if you want the nep to flower, be ready to sacrifice to have neps without pitchers for quite sometime...
