Chosha: Godly unit, or military academy bug?

BB:

I compared the entries for the upgrade to the army list. Here's the relevant section from battle_akademy.lua:

function tc_army_price_up(i) ---- íîâàÿ öåíà
return {3,15,250,100,9,50,80,190,19,75,80,85,85,6,8,370,180,50,95,370,45,10,11,35, 810,810,2,140,75,1,85,15,1,750,50}
end
function tc_army_af(i) --- íîâûé áîåö
return {"robber2","footman2","archmage","paladin","barbar ian2","bear2","bear_white","griffin2","beholder2", "snake_royal","snake_royal","kingthorn","kingthorn ","spider_fire","spider_fire","assassin","elf2","e nt2","unicorn2","assassin","dwarf","droideka_guard ","ingeneer","gorguana2","chosha","chosha","goblin 2","goblin_shaman","shaman_blood","zombie2","vampi re2","ghost2","imp2","demon2","archdemon"}
end

Assuming that griffin2 refers to royal griffins (Not sure what else it could be) the bolded entry should be the one that controls the griffin upgrade cost.
