Disregarding your husbandry issues, what size is the enclosure? The timing of the move and the fasting would indiciate to me that stress is the reason they stopped eating. With that said its been 2 months and they have not started eating so I would worry a bit as snakes that size should be eating voraciously. The problem could be a combination of your husbandry issues and perhaps insecurity if you're using a big enclosure; along with the catalyst of the move which triggered it all off. Seems to me like they need your husbandry issues corrected in order to get over the stress of the move.
