[FIXED]Estimeted Unit Cost randomize on scrollbar draging

[Kubby]

I believe it's not a bug, but a feature. Actual Unit Cost stays the same, and Estimate was intended to be uncertain. The bad thing is, that the way that uncertainty is introduce is unnatural, and the whole idea of uncertainty is just wrong. Player needs to have feedback and to know how much more exactly does he need to spend to achieve a better product.
