I have tried on a Mac and PC, Chrome and Safari. Whenever I try to save a edited reply I get a error code at the bottom of the screen in orange saying my content could not be posted refresh the page. Then I just loop through the same steps so I have had to delete my posts completely and re post with my edited comment.
I get the same error messages trying to edit.
