Changing descr_strat

I wanted to do minor change in descr_strat in mods\SS6.3\data\world\maps\campaign\imperial_campaign

I changed Stettin settings from:

settlement castle
{
level village
region Stettin_Province


year_founded 0
population 1000
plan_set default_set
faction_creator hre
building
{
type core_castle_building motte_and_bailey
plugin c_hansa c_hansa
}
}

TO

settlement
{
level large_town
region Stettin_Province


year_founded 0
population 3000
plan_set default_set
faction_creator poland
building


{
type core_building wooden_wall
plugin c_hansa c_hansa
}
building
{
type barracks town_watch
}
building
{
type market corn_exchange
}
building
{
type port port
}
}

But nothing has changed in game. Nothing. Why it is not working?



I also wanted to change Wroclaw and Stettin to have Polish rebels instead of German rebels, so I changed certain names in mods\SS6.3\data\world\maps\base in descr_regions, but it is also not working.

Where I making mistakes? What I am doing wrong?

Any changes to descr_strat require restarting the game before they are applied.
