I've had similar problems with some Arisaema species seedlings/first season tuberlets. Beautiful vigorous seedlings and enough produced to store during first dormancy dry, moist, cold, room temp, 3-8 months, in various combinations. Some species had in all batches remained dormant and slowly wasted away.
My best result for these was to throw seeds outside, ignore, and let sprout in spring and see if they come back the next spring..

I've had similar experiences with these plants - good autumn germination and subsequent growth - dormancy in spring, but that's it, they never make an appearance again. Perhaps even slight summer moisture is anathema to them.
This year I've tried them (and Placea ornata) in plain washed river sand with regular feeding, hopefully they'll be kept drier in dormancy by the sand and won't enter a slumber with terminal tendencies!
