Yesterday we have released the "Auto-approve" feature.
Despite our extensive testing, there was a bug that prevented it from working correctly. Under some conditions submissions by the auto-approved authors were approved in other communities instead.
We fixed the bug, but unfortunately there was no way to figure out which submissions by these authors were wrongly approved.
So we moved all latest submissions by these authors back to your moderation queues.
Please look through your moderation queue once again to sort it out. Auto-approve now works correctly.
It's great that the bug has been fixed. I also notice changes on menu which I think is a better one. Thanks!
