Unique units from Crusades

[RMSN NIKE]

Anyone knows a way to prevent the AI to get more than 1 of the unique units. I tried to, but had to undo the changes because no one can recruit the Power Center required units anymore after my attempt. I want to try the Muslim factions, but do not want to fight multiple unique units.

The same recruiting rules apply to the AI as they apply for you. What happened?

The AI controlled faction can get multiple unique units, I have seen Antioch getting loads of Canon of the Holy Sepulchre. And I have read on the regular forum that if you put your cities under AI control, there is a chance that you will also get additional unique units. I do not want to fight multiple unique units all the time. When I tried to change it in the campaign_script file, I tried to do what I did with the second wave of Norwegian reinforcement, by deleting the ; in front of the names of the unique units. When I started the new game, I realized that no factions can even recruit the units that requires the Power Centers. I did the same thing to the second wave of Norwegian reinforcement scripts, now they have 3 waves and only lose 2 of 3 King's purse increases. Even though I decreased the standard King's purse and increased the 2 deductions, they still have the highest King's purse when any players play the factions, since AI always gets King's purse bonus.

You're probably dealing with the wrong script, from the sound of it. The unique units are dictated entirely by...

...and from the looks of it, the script shouldn't affect only AI or humans. Because it deals with counters, it should work fine. If the CPU is getting more unique units, it may be because of the spawning script in the game.
