A georeference in one of our objects seems to have misbehaved somehow when placed; the entry is behaving as though the entry saved only partially, and is not actually displaying the reference. (First image)
This reference cannot be deleted - the 'x' link neither responds nor returns any kind of error. Other references can be added and deleted normally, but they cannot be saved, as CA returns an "entry was blank" error (second image). The entry as a whole cannot be duplicated either; CA returns a "Could not duplicate" error with no explanations.
Fields in other sections can be edited normally, but georeferencing for this object in particular is totally unusable at the moment.

It was a character escaping issue caused by the apostrophe in the place name. It is fixed now both in the GitHub code and on your running system.
