create_unit "Tara" "celtic druids" works
create_unit "Tara" "celtic spearman" works

create_unit "Tara" "celtic crossbowmen" does not work
create_unit "Tingi" "berber mountain men" does not work

The bottom 2 that are shown are listed on the above list (like the top two) but they do not work...any idea?

All I am trying to do is get 1 set of INF, 1 set of Cavalry and 1 set of Archers for every faction that will work...:(
