I was starting to modify/rebalance the default races some when i realized that i had to change the ability bonuses to cover some reces abilitys. No problem there and i got all to work but then i was thinking that some races might have flaws. An axample might be a race that are extravagant so they should have a penalty in Economics.

Now to my problem:
I can without a problem make the extra entry for the extravagant perk and give it a negative bonus and cost. The cost part works as i want but not hte bonus part. If i enter a penalty for 10% ingame i get (+-10%) and the sum of 0 not -10%. Now my question is do anyone know how to make the game understand negative entries in the ability bonuses?
