Recently edited objects disappear from the object explorer pane after editing an object in designer. For example, changing columns on an existing table which prompts to update a related table will result in the related table being highlighted and the table I was editing disappear from the object explorer pane. The missing object only reappears if I manually refresh the pane. If I don't notice that this has happened, it can be very confusing scrolling through a list of objects trying to finding recent changes. This is a bug.
