So is my symptom really a problem? Can other people assault cities with just an elephant army? Perhaps I should re-install R:TW?

Here's my unit entry for the elephant above:
Code:

stat_fire_delay  0
stat_food        60, 300
stat_cost        1, 2690, 490, 270, 410, 2690
ownership        slave

and the mount entry for the elephant:

Code:

I'm thinking about re-installing Rome and see if there was a problem with my installation...


Are other members really able to assault cities with just units of elephants?
