Hi Clint,
Sorry for your disappointment with Lime Twister. I'm the breeder of this plant and I have a couple of ideas.
It seems to lose the colorful variegation when it gets extremely dry and dehydrated. The good news is that the variegation is still present and will recover its showiness with semi-frequent watering. I've had the same thing happen to my very old and rootbound stockplants of Lime Twister. However, when I placed in fresh soil and watered, they colored up in about 8-10 days.
Also, next spring, they should put on a great color show.
Hope this helps!
Chris Hansen
