Google has posted an announcement thread at Google Groups saying they hope they have fixed a bug that removed ownership status of some Google Group owners.
In short, Google Groups pushed out a new update that caused the removal of ownership in some instances. Google believes they have addressed the issue and returned ownership status to those impacted by this change. Google said:
We believe that we have identified all of the users who lost owner or manager rights as an indirect result of our error, and we have fixed those cases as best we could. In some cases, we don't have enough evidence to say that you should be an owner, and in those cases we've made you a manager; you can ask another group owner to promote you or follow up in the help forum. In either case, if you do not like the email address or the nickname that we used to resubscribe you to your group, you can change it by clicking on the "Edit my subscription" link in the group, and modifying as appropriate -- there's a little menu for email, and a field for nickname.
Those impacted by this issue had to have meet the following conditions:
- you have multiple email addresses associated with your account
- you attempted to log in while the bug was live
- you subscribe to or own groups under the different emails in (a)
Forum discussion at Google Groups.
