Sometimes it's necessary to select multiple segments to perform a road closure either for MTE or for a conventional closure. After you have several segments selected, you accidentally select a node and all work is lost (the section disappears). I suggest making a modification that prevents the disappearance of the selection of these segments and notifies the editor that you selected a node and it will not be possible to make the respective closure (before or at the moment of trying to save). Obviously the idea is to give you the opportunity to remove the node from the selection and continue with the work.
