game crashes when changing to a custom race

[FurryNoseBooper]

the race in question in Ungulate (by Bad Dog) and it seems to be very specific, if I change from default nord to ungulate, it CTD, if I change to a default right ( I.E. nord to orc ) and than change to ungulate, it works, but if I change the gender it CTD, if I go the most round about way possible... nord >> imperial >> female >> ungulate, then it works, but it CTD at random when customizing appearance in RaceMenu

helppppppp?
