cannot increase town

[attyla]

Hi
I have no idea what's going on. I've added more conditions to upgreade some of towns structures in my EDB (for example i have to build roads and farms to have possibility building a harbour). i've not added any conditions to increase level of the city/castle.
Unfortunately, after this change I cannot improve level of some cities after announcement about city level improve possibility
One more thing: I cannot improve level of city after changing the castle to the city. If I want to improve level of city I have to change city to the castle, improve level of the castle and change castle to the city back.

You can find belowe 2 known cases (descriptions from desr_strat)

settlement castle
{
level large_town
region Corinth_Province

year_founded 0
population 1000
plan_set default_set
faction_creator byzantium
building
{
type core_castle_building wooden_castle
}
building
{
type castle_asymilacja_b mustering_hall
}
}

and

settlement castle
{
level large_town
region Ragusa_Province

year_founded 0
population 1000
plan_set default_set

}
}

You have to keep the level of the settlement according to the level of the core_building.

Please note that one example shows level large_town and type core_castle_building wooden_castle
The next example shows the same level but has the higher core_building level of 'castle'

The first example is incorrect as the level town corresponds to wooden_castle
The second example is correct

These are the population level ranges for core buildings.

population_levels
-- city -- (always min 400)
village     base    400,  max   1500,  upgrade    800
town        base    800,  max   3500,  upgrade   2000  wooden_pallisade
large_town  base   2000,  max   9000,  upgrade   6000  wooden_wall
city        base   6000,  max  18000,  upgrade  12000  stone_wall
large_city  base  12000,  max  36000,  upgrade  24000  large_stone_wall
huge_city   base  24000,  max  72000                   huge_stone_wall

-- castle -- (always min 400)
village     base    400,  max   1500,  upgrade      0  mott_and_bailey
town        base    400,  max   3500,  upgrade      0  wooden_castle
large_town  base   1500,  max   9000,  upgrade   4500  castle
city        base   4500,  max  13500,  upgrade   9000  fortress
large_city  base   9000,  max  18000,  upgrade  18000  citadel

A settlement's population can be anything from base to max but it's best to keep any given population level below the upgrade level for that size settlement.

eg non-castle settlement

Village <=799
Town <= 1999
Large town <=5999
City <= 11999
Large city <= 23999
