Well, I'm both excited and nervous once again. The good folks at the Nirvana Help Desk just responded to my message and let me know that, while they had no real idea about what might have happened, they felt bad for me and would replace my order. It's already been reclassified as resent, so I imagine they are on their way. I will say I've got a bit more anxiety this time around, and sort of wish I'd ordered from a seed bank that's housed in a country with a wider export business. Although Nirvana has been very generous; I didn't expect them to send another order at their own expense, and if I get the seeds without issue this time, I may just stick with them because of their customer service.
