Units

[Ashdnazg]

Probably just an error, I doubt CA hand-edited the edu so it could be that someone added the same attribute twice in whatever program they used to generate the file.

Interestly theres no reference to the command ability there, theres a few others missing too, the hide_'s are found in another part of the exe but theres no mention of general_unit. Theres also a number of other attributs in the edb which I cant find reference to, knight, gunmen, crossbow, guncavalry etc which are possibly ai related?

Sounds very probable.
Perhaps some attributes aren't checked in loading but only in the related procedures.
Is the game loading with non-existing attributes?
