References 5-8 were not saved
At https://en.wikipedia.org/w/index.php?title=User%3AThryduulf%2Fsandbox&diff=566402676&oldid=566401436 only four of the 8 references I added were saved.
The second references for each statement had the same title as the first but were a different URL. They appeared in the editor as being there (see attachment) but were silently not saved.
