Frontier Spirit Payback
I found Frontier Spirit, a ruler trait has an issue, at least on ver. 2.2.7. It is supposed to discount colonizer ship cost 35% (each 70 of food, alloys and comsumer goods), but it doesn’t.
It is because "ship_colonizer_cost_mult" modifier doesn’t work. Fortunately, "planet_colony_development_speed_mult" modifier does work as it is supposed. And sponsored colonizer ships can get the discount as normal.
This mod is to patch the issue. It will give you each 80 of food, alloys and comsumer goods (40% of the cost) when your colonizer ship is built. Think the 5% as an interest.
If you use "Additional Traits" mod, this mod will get payback for Pioneers trait (supposed to discount colonizer ship cost 30%), you will get each 70 of food, alloys and comsumer goods (35% of the cost). If you are a hivemind, you will get each 175 food and 70 alloys (35% of the cost). But, if you have Rooted trait, 35% of cost will be upcharged…
If you use "EUTAB – Ethos Unique Techs and Buildings" mod, this mod will get payback for Establish Voluntieer Union technology (supposed to discount colonizer ship cost 25%), you will get each 60 of food, alloys and comsumer goods (30% of the cost).
