Description
For the Netherlands' focus tree, the "Ship-A-Day Sinking Quotas" focus still adds a tech bonus to submarine doctrine. Since NSB, doctrines are no longer techs, so this does not work. Instead, it should be a cost reduction towards said doctrine.

Steps to Reproduce
Open up the file netherlands.txt under national focus and see the following:

focus = {
id = HOL_ship_a_day_sinking_quotas
available = {
has_war = yes
}
prerequisite = { focus = HOL_de_vaarplicht focus = HOL_the_singapore_conferences }
icon = GFX_goal_generic_navy_submarine
x = 1
y = 1
relative_position_id = HOL_de_vaarplicht
cost = 10

available_if_capitulated = yes
search_filters = {FOCUS_FILTER_RESEARCH}
completion_reward = {
add_tech_bonus = {
name = HOL_ship_a_day_sinking_quotas
bonus = 1.0
uses = 1
category = ss_tech
}
add_tech_bonus = {
name = HOL_ship_a_day_sinking_quotas
bonus = 1.0
uses = 1
category = submarine_doctrine
}
random_unit_leader = {
limit = {
has_id = 981
}
add_attack = 1
add_maneuver = 2
add_coordination = 1
}
}
}
