Update: In which my vote is saved

Once the time zones aligned right today, I called another number I found on the county voting website. After a while on hold (but thank goodness no more forwards to voicemail) I explained the situation to a human being, who asked for my name, checked my address, and told me he'd make a note of the resealed envelope so it won't be taken for a sign of tampering when my absentee ballot comes in over there. That's a lot more than I expected. I think I can relax a bit now. *knocks wood*
