EDIT: this issue has been reported in the past, and has not yet been fixed. See Post #5 where there is a link to the original Bug Report Topic, which also includes the Cause of this Issue. See Post #6 as well which contains a video clearly showing the Issue.
EDIT2: this issue is much worse than I originally thought. It has nothing to do with Entities whatsoever. Make a partial Payment to a Ticket and close it. Open the Ticket, and immediately Close it. At this point, the [Payments]
table now contains records for the Ticket which are corrupt (NULL values).
