This issue has been resolved. The avatar server which provides search functionality was overloaded by recent new functionality added to developer submissions pages. This functionality has been removed. Members checking their submission pages will see the following changes:
1 - The list option will show up on every closed submission.
2 - The unlisted tab from my submissions page has been removed.
We recognize the functionality was useful to our members, and will be looking into alternative methods of providing it which do not severely impact search functions.

Our search system is experiencing technical difficulties.
We are investigating.
This issue is causing Places search to show "0 records retrieved", and all group search functions such as Co-Host selection and Sending Invites to Groups to not work, they will show no groups.
