im trying to make my own mod, and ive made a new system where the nomads are trying to retake one of their old abandoned bases, and i cant get the encouter properties right

[Object
nickname = EW07_lair_01
ids_name = 10901
ids_info = 0
rotate = 0, 0, 0
pos = -18616, 0, -9662
archetype = lair

[Zone
nickname = Zone_EW07_pop_ambient_01
pos = -18622, 0, -9664
rotate = 0, 0, 0
shape = SPHERE
size = 8190
comment = Lair Population
sort = 51
toughness = 20
density = 10
repop_time = 30
max_battle_size = 10
pop_type = Background
relief_time = 35
population_additive = false
faction_weight = fc_n_grp, 20
faction_weight = gd_bh_grp, 20
faction_weight = rh_n_grp, 1
faction_weight = li_n_grp, 1
encounter = area_nomads, 20, 0.250000
faction = fc_n_grp, 1.000000
encounter = area_bh_assault, 20, 0.100000
faction = gd_bh_grp, 1.000000
encounter = area_assault, 20, 0.250000
faction = rh_n_grp, 0.800000
faction = li_n_grp, 0.200000
encounter = area_defend, 20, 0.200000
faction = rh_n_grp, 0.650000
encounter = area_bh_defend, 20, 0.100000
faction = gd_bh_grp, 1.000000
encounter = area_scout, 20, 0.090000
faction = li_n_grp, 1.000000

ive also got the [EncounterParameters part at the top of the ini file

some times the nomads will show up, sometimes the rheinlanders will show up, but hardly both/all of the people i wanted.

I was also thinking, could i do different population zones for everything?
