Pro Sites Subscription Suddenly Downgraded

Here are the steps I took:
- Created a new site
- Upgraded the site to one of my paid plans, using Stripe as the payment gateway
- Got to the "Success" page and clicked to access the dashboard for the newly upgraded site

All was well for the first minute, but I was then unable to access the dashboard for the newly upgraded site. I checked the logs and here are the last two entries:

2013-06-04 12:03:59 am : Pro Site status expiration extended until June 17, 2013.
2013-06-04 12:04:00 am : Pro Site level downgraded from "Premium" to "".

What happened? Is it because I'm in test mode? Because Stripe is in beta?

P.S. I should mention that I have a 14 day free trial period enabled, and that this transaction was done on the first day of the free trial.

P.P.S. Testing without a free trial yields only slightly different results. The log now reads:

Pro Site status has been withdrawn.

So there appears to be some kind of glitch associated with the Stripe gateway implementation. Is this something others have experienced? If so, is it something I can expect to be resolved very soon?
