If you are in a section of a zone where there is no world map region text (i.e. the region text is the same as zone name; e.g. 51.37, 40.72 Hallowfall or 50.63, 71.24 Isle of Dorn), then a default mount is summoned instead of a zone specific mount.
I fixed the issue by doing an additional check on subZone string length and will raise a pull request shortly.
