Problems with using the Make comments or override grade option

The problem seems to be with the comments. I have recieved 2 types of errors

1) could not find any user attempts and a changes saved prompt back.

2) could not insert entry in question_sessions.

It would seem that if a comment and manual grade has been entered that this should somehow be indicated. I noticed that the x/x marks was not displaying what was being manually graded even though the final grade was changing.

I know that this is new functionality being worked on and developed. I will attempt to look more into it and provide information as I stumble across it. Please let me know if there is anything specifically that I can do to help.

Peace - Anthony
