Reply Issue

I loaded a page and started reading comments. I found one to which I wanted to reply and wrote out my response. Upon hitting "save," the page hung. I was able to figure out that this was because the person to whom I was replying had deleted his comment in the meantime. Fair enough, but it turns out that my comment still wound up getting posted. Instead of appearing as a reply, however, it appeared on the top level as if it were a comment submitted directly in response to the picture. Seems like the comment should just be rejected in that case rather than posted to the top level with no context to make sense of it.
