Sounds like midwinter Brumation to me. if your temps are colder than they had at NERD they may think its breeding season, when it is common to go off of feed. Try raising your temps a little if they arent optimal. I'd talk to NERD and ask for some advice too.
I agree. They will still be the owners of the first Burgundy SuperPastel and I bet they are already working on getting some morphs ready to breed to it.
Now its all up to your hardwork and diligence to produce that new morph. Hopefully the morph gods smile on you and you get one in the first clutch.
Best of Luck!!! Post some pics of the parents and your pair for us to drool over!!!!!
