Something is definetly not right. Something has messed up their day night cycle or seasons. They usually don't go into full estivation as in hibernation unless conditions are right for it. Usually a slow and gradual drop and temp and humidity over a week or 2 which makes their body switch into winter hibernation or dry season hibernation. It is not normal for them to go under this long with the conditions not being right. You might have to find a way to slowly bring them out of it. I'm not sure what's going on but they don't just go into long term sleep mode like that.
