Hello heylemmonhead, you've added a tag "name=free library" to an existing node in norway. Thus your deletion of the whole node with changeset 139765245 although affected the highway, where it has been a member of. 
I've reverted changeset 139765245 to restore the node and removed the accidentially added name tag.
Before trying to revert unexpected changes, please have a look at the history first, to check what really happened.
