The MidAmeriCon II, which announced on February 7 that all online Hugo voting PINS had been sent, gave a status report on Twitter and Facebook today about a problem that will require some to be sent again:
Our Hugo team have identified an issue with our Hugo Pin mailing software which prevented some people from receiving their pins.
We are working to resolve the problem and will be resending pins to everyone as soon as possible.
We are very sorry for the inconvenience and delay this has caused.
