I have started a new game, custom race, normal difficulty. I have chosen bonuses/starting technology/government in such way that I have no military or social manufacturing bonuses. I checked in the abilities window that I have no those bonuses. Then I put the spend slider into 100% and I put the whole amount either into military production or into social production. I also put some ship to build and some building to construct on that first planet, so that I actually was spending money. The planet have 24 pt initially so I expected the following:
Put everything into military. Spend 24bc get 24mp
Put everything into social. Spend 24bc get 24mp
What I got though is the following:
Put everything into military. Spend 24bc get 26mp
Put everything into social. Spend 24bc get 26mp
It looks like I have 10% bonus for whatever reason!
Now, I created the custom race again, but this time I put 10% bonus for military, and 10% bonus for social. I did check the abilities window again that I indeed have exactly 10% in both. Now, because of the above results, I have no idea what to expect, but what I got is the following:
Put everything into military. Spend 26bc get 28mp
Put everything into social. Spend 24bc get 26mp
I have no idea what is going on. Why are military and social different now?? I have checked several times, and this is the behavior of the game. If it is not bug, then what is it?
