I have a problem with a simple script for my great campaign (running Kingdoms atm); it's supposed to decimate pop in a settlement at the occurrence of an event called "test". Here's the code:

monitor_event EventCounter EventCounterType test
and EventCounter = 1

console_command add_population Paris -3700
terminate_monitor
end_monitor

Obviously, in descr_events I put:

event historic test
date 1

...and it pops-up just fine on 1081.

BUT: the population does not decrease.
I also tried this version of the script:

monitor_event EventCounter EventCounterType test
and EventCounter = 1

add_population Paris, -3700
end_monitor

but nothing changes at all. Any idea? PLEASE
