Lost users, vanished right in front of my eyes

Another idea:

• When the data disappeared, did you moments before delete a column with row owners applied to it?

Yikes My User Profile has gone screwy

Nathanael made no mention whatsoever of RowID. He referred to row owners, which is a completely separate thing. There is a known bug where if you delete a column that has row owners applied, sometimes all data in the table will disappear. So I suspect that Nathanael was postulating that you might have triggered this bug. The workaround is to add the column back.
