Thanks! So that's what happened to all my money.
You are right, income is affected normally by the death/growth scales, for all ages of Abysia.
Supplies are not affected at all by having death/growth scales.
And RamsHead, I was also wrong about the penalty in my post above this one. I mistakenly thought that it was just the death scales that had no effect. Since you don't get the benefit from growth scales (though as Micah says the income affect is buggy so you do get the +2/4/6% income) either, it is a penalty.
