I've encountered this, my feedback is in the omniplan(ohwowIcantpronouncethis)@omnigroup.com inbox. Basically, select the line item that no longer has any child/dependent/"indented outline" entries below it. Then, select the "Task:Information" inspector. You'll see that same task item there, categorized as a "group" in the dropdown below the task name. Selecting "task" from that dropdown redraws the outline display as expected for a single independant line item.
