A 3-day lock is more a punishment to everyone else in former Kabrinskia as it means at the very least three more days before Allison steps down and we can actually do something constructive with the duchy. And the city's set to starve in less than two days, oh joy.
I think you're going to find that it's impossible to for the duchy to "defect" back to Kabrinskia, even if the bug had not been fixed. The only option, IIRC, is to secede from Astrum.
