I hope it didn't also. and I agree it shouldn't have been shipped but if you do ship a gravid specimen it should be top notch packaging with a heat pack this time of year. and this guy failed. He also said he had no choice but to sell his collection.
I wouldn't worry about them being cold for a 2 or 3 days, even tropical stuff can take that for a while. I also read that transvaalicus often live in areas that have a pretty low night time temps and probably get caught out under a thin rock now and then when it gets pretty cool. I forgot exactly what the cooler night time temps were in parts of the natural range though.
