As well as dragging the road/path junction node to a wall, you also dragged a ruin node (some distance away) to a river and a solar panel into a field. See https://overpass-api.de/achavi/?changeset=136912924
Reverted changeset and reapplied the good change of road type residential to unclassified.  
Please review how this happened, for example how you move the map while editting.  
Also please always set specific meaningful changeset comments so others know what you intended, eg 'change road type to unclassified' here, so that intended vs unintended changes can be understood if the changeset(s) need to be reviewed.
