If you have a complex transclusion (e.g., a succession box), and you try to rearrange the order of the items, and if one or more of those items is a template that contains a parameter, then some or all of the parameter-containing templates will silently disappear. See https://en.wikipedia.org/wiki/Wikipedia:VisualEditor/Feedback/Archive_2014_1#Add_content_and_other_transclusion_mysteries for complaints. Diffs of resulting problems: https://en.wikipedia.org/w/index.php?title=User%3AFram%2Fsandbox&diff=596891776&oldid=596891699 https://en.wikipedia.org/w/index.php?title=User%3AFram%2Fsandbox&diff=597044161&oldid=596891923
