Exception Type: GEOSException at /admin/geo/borders/136/
Exception Value: Error encountered checking Geometry returned from GEOS C function "GEOSGeomFromHEX_buf".

The copy suffered much the same problem.

If I've not missed anything substantial (which is quite an If, honestly) I'd call something that causes data loss to be Critical.
