Several times, I have run into an error when submitting an edit. It's usually when creating new people. Edit #70821 is the most recent occurrence. If it's anything like the last time this happened (Edit #65404), it will sit as "Pending" for a while until it is eventually automatically denied.
One thing it does, though, is create person pages for anyone new. But the pages are empty.
Since this happened the first time, I only edit in small chunks now. Things would be so much better if I didn't have to do that, but if I didn't, I'd be afraid that I'd lose the work.
I haven't contributed as much as I'd like to since these errors began, and then happened more than once.
PS - a couple of things that have come to mind since...both times that I lost big edits, I had my browser window filling about 3/4 of the screen, in order to see pictures of the credits on the other 1/4 of the screen. I can't recall having an error when I had my browser filling the whole screen. Edits seem to happen faster when it's like that, too. Could that be the problem?
