First of all, thank you for your reply!

Unfortunately, the code you proposed didn't work.
And: I definitely don't why - it seemed quite reasonable to me...

I must say that either "add_population Paris -3700" and "add_population Paris, -3700" do work in the in-game consolle. So what ?!?!?!?

Maybe it's a matter of version: I'm running Kingdoms, which should be equal to medieval + 1.2 patch.

PLEASE PLEASE
