Ptolemaioi and Pahlavån-i Grivpånvar

[MarcusAureliusAntoninus]

Not all units go by the same name internally as they do in game. Some have had their names changed over the EB versions and some simply have generic name, such as "eastern cavalry elite cataphracts" or some such name. You could look in the ...\EB\Data\Text\descr_units.txt for "griv" and it should have the internal name next to it.

As for recruitment, that is much more complicated. It helps if there is a unit that shares the same recruitment you want.
