Since the server update went live on Monday, I've had a sporadic problem where when I try to add a new release, the edit to add the release will go through but the edits to add the medium and any external links will not. When this occurs, I cannot leave the release editing interface after clicking "Enter edit"; the button will either go grey and cycle for a while before reverting back to being clickable or it will just lock up, staying on the "Submitting edits..." screen indefinitely.
To make matters worse, if I try to go to the newly-created release and fix it, the problem will repeat itself. I will be left completely unable to add a medium or external links to the incomplete release.

I am currently running 64-bit Google Chrome version 41.0.2272.118.
