List is suffering from numbering glitch...again

While working on reordering a large list earlier this week, I encountered an error and posted about it in this now-closed post. The error was fixed and I was able to resume working, but after a few days of working on it, I encountered the same error again. Would someone please send another ticket to have it fixed again? Thanks in advance.

P.S. I successfully reordered 330 out of 1028 list items before running into the same error, so there's a greater-than-zero probability that I will have the same error one or more times before I'm done with this project, so maybe it would be easier to not close the post right away after 'fixing' the issue? Just a thought.
