Skype To Go setup destroyed

(A backdrop of this is that my Unlimited World subscription was automatically renewed this week for another year, which may or may not be connected with the problem.)

This morning, I found that my Skype To Go number was no longer working. I came to skype.com and saw that it thinks I have no Skype To Go number, and offered me to get a new one. What's worse, it had also forgotten all my speed dial contacts and I had to recreate them, which was annoying.

So I got a new Skype To Go number and recreated my contacts and now everything is working again. Still, it was bizarre. I hope I don't have to do this every year upon subscription renewal.

Another bizarre element is that skype.com thinks my previous SkypeToGo number was online number, and says "Your Online number +1..... has expired. Reactivate" I don't want to do that, and there seems to be no way to get rid of this notification either.
