Not sure but there may be more you need to change. Try that first I would propose and see where that gets you. I only know how to do basic editing so I dont know if this will get you the desired effect or not. Dont forget to back up your files! Or maybe just change the type to steppe cavalry grivpanvar. Im really not sure to be honest. Good luck to you.

nope i tried it with the changes both ways
type steppe missile cavalry sphanvade and

type steppe cavalry grivpanvar

hmmmm i am not really sure what is the problem!!!!
this truly has me stumped!!!!! i did not change the ;449 to the ;317 though .... thanks in advance if somebody figures it out
i would truly be thankful if somebody would assist me and just give me some closure

just bumping
