Issues with the Ajax features

I've noticed that recently there have been issues with the quick post editing feature. Sometimes I get a "Vote Now" button instead of "Save" button when quick editing. At other times when I edit a post a second time I may get incorrect post contents, for example if I had edited an earlier post and then edit a later post I may get incorrect text (I didn't reload the full page between edits). However at least once I've got an incorrect post on first edit attempt.

Most often these errors get fixed by choosing Cancel and trying again, but when I'm on mobile connection it can get pretty frustrating to wait at times :) Also, I have had these problems with a cable connection and a mobile connection, so it isn't about bad connectivity only.
